My Top-5 Roleplaying Games of All Time

Over at the “RPG Pub” there is a thread asking people to post their top-five favourite role-playing games of all time.

Here’s my list. Reflecting on the role-playing games that I’ve played over the past forty-five years or so, I’d say that my top five have to be the following:

Middle-earth Roleplaying (MERP)/Against the Darkmaster (VsD)

My first “real” campaign involved MERP and ICE’s beautiful maps and detailed campaign modules. MERP – and its descendant VsD – captures what I like the most about Rolemaster – the flexible class-based character development system; the detailed, vivid critical hit charts; the overall coherent rules framework – but without the large volume of charts and details that (IME) bogged down RM in actual play.

Some of my fondest memories of playing RPGs involve MERP and my two favourite campaigns of all time as GM (one still ongoing) use VsD.

Mythras 

I started playing this in 2011 – back when it was still being published by Mongoose and was called RuneQuest II (i.e., MRQII) – and haven’t stopped since. I’ve played in campaigns set in the Young Kingdoms (“Elric”), Mythic Britain, Mythic Babylon, Beyond the Mountains of Madness (the CoC campaign adapted to Mythras), and now Lyonesse, as well as in several “one-shots” or short campaigns (Mythic Greece, Luther Arkwright, Meeros, etc.). A really excellent system overall.

Call of Cthulhu

I haven’t played CoC since 2017 and I’m in no rush to do so again soon. But I’ve run a lot of CoC over the years – almost always as GM (er, “Keeper”) – and I’ve always really enjoyed it. I’m pretty sure it’s the game I’ve run the third most often (after MERP/VsD and AD&D). The scenarios are generally excellent (although some needed work). My only regret is that I have yet to run one of the “classic” campaigns for it (although I did play through BMoM using Mythras).

Dungeons & Dragons/Advanced Dungeons & Dragons (TSR era)

Like most RPGers, I started with D&D and spent a lot of my early gaming days (the early 1980s) playing and running AD&D (and I’ve returned to it from time to time since then). Reading Gygax’s hardbound volumes not only improved my vocabulary as a wee lad, but also sparked my imagination. They were the works of a disorganized creative genius. I still treasure the classic modules from that era as well. Although aspects of the system never failed to frustrate me, the game will always have a special place in my heart.

Stormbringer/Elric!/Hawkmoon/Corum 

(i.e., BRP “Eternal Champions” games)

I don’t really have any interest in running these BRP RPGs now – Mythras has largely filled that space for me – but I still have these books and really enjoyed these (closely related) games back in the day. 

There are other games that I like and other games I hope to try – but these are the games that I consider my all-time favourites.

Feel free to post your "top-5" lists in the comments, if you like. I'd be curious to learn what games have stood "the test of time" for you.

Lords of Chaos! Free League also producing a Stormbringer game?

Well this is a bit confusing. Just two days ago I mentioned that Goodman Games announced that they will be producing material based upon Michael Moorcock’s “Elric” novels for the Dungeon Crawl Classics and 5th edition Dungeons and Dragons role-playing games.

Now it looks like the Free League also will be getting in on the Eternal Champion multiverse action, with Legends of Stormbringer, based upon their Dragonbane system. (Hat tip to Todd S for alerting me to this in his comment on my previous post.)

“Today, we are thrilled to announce Legends of Stormbringer, a new officially licensed tabletop roleplaying game based on the iconic fantasy works of Michael Moorcock, planned for release in 2027.

Legends of Stormbringer will carry you into the Young Kingdoms – a world of dying empires, warring gods, and doomed heroes – and bring Moorcock’s richly imagined setting to the tabletop using rules mechanics based on our award-winning Dragonbane RPG. The game will feature the same accessible, dynamic, and deadly approach that has made Dragonbane one of our most celebrated titles.

Returning to the Young Kingdoms as setting writer is Richard Watts, whose work on previous Stormbringer RPGs helped define how generations of roleplayers have experienced Moorcock’s world.”

This announcement is a lot more interesting and appealing to me than the one from Goodman Games, given Watts’s involvement and the use of Dragonbane instead of DCC or 5e D&D. I have yet to actually play Dragonbane, but I own and have read it. My overall impression of the game is quite positive. Moreover, since Dragonbane is descended from the Basic Roleplaying System – just as were Chaosium’s various editions of Stormbringer – there is greater continuity here with previous Eternal Champion role-playing material than there is with Good Games’ projects. This continuity is reinforced with Watts’s involvement.  

But I have to confess that I’m a bit confused by these multiple announcements! Given the setting in question, though, I suppose that this kind of Chaos is appropriate. 

By Arioch!

The return of Elric?

It looks like the multiverse of the Eternal Champion Elric will be returning to the world of in-print role-playing games thanks to Goodman Games:

“Goodman Games is thrilled to announce a licensing agreement to publish official tabletop role-playing material based on Elric of Melniboné, the iconic sword & sorcery character and setting created by legendary author Michael Moorcock! 

The Classic Era of Elric will include a line of sourcebooks, adventures, maps, and additional supplements, all designed for compatibility with both Fifth Edition and Dungeon Crawl Classics role-playing game systems. The project is scheduled to launch via crowdfunding in 2027. Products will be released following the successful campaign and will be available at game stores worldwide.”

Despite the influence that the early Elric stories had on me (and I remain fond of them to this day), I have to confess that I’m not all that excited about this. One reason is that the setting will use 5th edition Dungeons and Dragons and Dungeon Crawl Classics – two systems about which I have decidedly cool feelings. DCC was a poor fit for another cherished fictional setting – Jack Vance’s Dying Earth – and I doubt that it will be appropriate for Elric (at least not without some heavy reworking). 

A second – more decisive – reason is that I already own a lot of "Elric" role-playing books: three editions of Chaosium’s Stormbringer (including Elric!, which is the same system as 5th edition Stormbringer), and a lot of supplemental books for those editions, as well as all the Elric of Melniboné books that were published for Mongoose’s Runequest II (MRQII) system. (MRQII, as many readers no doubt know, eventually evolved into Mythras.) So I already have more than enough Elric material – as well as some Hawkmoon and Corum material – to run multiple campaigns, all using RPG systems that I much prefer to both 5e D&D and DCC.

But who knows – maybe the new material will be good! Time (and funds) permitting, I may check out what Goodman Games produces for everyone’s favourite melancholy albino. 

What roleplaying games are you playing now? What games do you want to play?

I've been writing this blog for almost seventeen years now. Yet I've rarely addressed any questions to you, the human beings who look at these posts from time to time. But I'm curious about who actually visits this place (aside from the bots). I'm interested to know what game(s) you play. 

As I explained in my previous post, the roleplaying games that I've been playing have shifted over the past two decades. Early on, I was focused primarily on "Old School Renaissance" games like Swords and Wizardry (and developed some house rules for it, many of which were later integrated into Crypts & Things, which I also played back in the day) and 1st edition Advanced Dungeons & Dragons/OSRIC. I also occasionally ran Call of Cthulhu. 

Then, in spring 2011, I started playing in a "Young Kingdoms campaign" that used the Runequest II (MRQII) rules. (How could I refuse? The Gamemaster was one of the co-authors of the system!) This started a long period -- continuing to this day with Lyonesse -- of playing versions of the game that is now called Mythras (MRQII and Runequest 6 were the immediate ancestors of Mythras -- all written by Lawrence Whitaker and Pete Nash). I also continued to run Call of Cthulhu from time to time (winding up a sporadic campaign in 2017). And in 2017-2018 I ran an Adventures in Middle-earth campaign.

For a few years I ran a campaign using Dungeons & Dragons 5th edition in the "Gygax version" of the World of Greyhawk. (I eventually switched to the 5e-based Into the Unknown system, but ItU is close enough to 5e that I regard the whole campaign as my "5e" one.) I wanted to properly "try out" the current version of D&D and we ended up continuing until the characters reached 6th level. While that campaign was fun, I realized by the end of it that I had no desire to ever run 5e D&D again, at least for an extended period of time (I did run a couple of sessions of 5e for some kids last fall -- one of my few "charitable acts" as a RPGer).

Over the past few years, as GM, I've primarily run Against the Darkmaster. One campaign, set in Middle-earth, wrapped up a few months ago (although I have a "epilogue" set of adventures planned for the same characters sometime in the future). The other, set in my homebrew world of "Ukrasia," is still going strong. 

So these days, I mainly GM Against the Darkmaster and I mainly play Mythras (I'm leaving out various "one shots" of different systems here). I would like to try out Dragonbane sometime, as it strikes me as similar to Mythras in many ways but is much "lighter" in terms of both rules and tone (the similarity shouldn't be that surprising, since both games are descendants of the "Basic Roleplaying" system created by Chaosium almost five decades ago). 

What about you? What games do you play these days, either as GM or player? What game(s) do you want to play?

There and Back Again: My Circular Role-playing Journey

I’ve talked about my personal history with the ‘Old School Renaissance’ or ‘Old School Revival’ (OSR) in the past at this blog (e.g., see this post from 2022). But some reflection on the games that I’ve been playing in recent years has prompted me to scribble some further thoughts. (My apologies for being a bit self-indulgent here …)

[Saruman by Angus McBride]

It’s been an interesting journey. I was ‘floating around’ at various role-playing games fora during the early days of the OSR over two decades ago. Disappointment with 3rd edition Dungeons & Dragons – and nostalgia for my early days of gaming – led me to dig out (and in some cases repurchase) my old Advanced Dungeons & Dragons, Basic/Expert Dungeons & Dragons, Rules Cyclopaedia D&D, and other out-of-print RPG books. I was excited – and later disappointed – by Castles & Crusades in its early days. (I wrote positive reviews at RPG.net of both the C&C box set and Players’ Handbook, but eventually came to find the atrocious editing by Troll Lord Games intolerable.)  

I started this blog in 2009 in order to post some rules ideas for Swords & Wizardry (S&W). Some of my ‘swords and sorcery’ house rules for S&W appeared in early issues of Fight On! and Knockspell. Eventually, many of those rules were incorporated into Crypts and Things. So I guess that I contributed – albeit in a small way – to the creation of OSR “stuff,” at least early on. 

But I haven’t really been that engaged with the OSR for about a decade now. I still follow it to some extent. I mean, I have Dolmenwood and Shadowdark, as well as the more recent versions of S&W, and a few other things. I’ve backed the forthcoming ‘3rd edition’ of OSRIC (the original “retro-clone,” in this case of 1980 AD&D). While I regret some of my purchases, overall I find that there are still interesting things being produced. But I don’t really use any OSR (by which I mean here ‘TSR D&D-derived’) systems anymore, and haven’t for years. They just don’t appeal to me that much these days. I think that, given my tastes, there are superior alternatives available. I guess I shouldn’t be surprised by this. I sort of thought the same thing about AD&D/D&D around 1985.

Almost all my gaming these days involve either Mythras or Against the Darkmaster (but sometimes my groups will play ‘one shots’ of other things, e.g., Mothership or Delta Green, and I’d like to run some Dragonbane someday). I find these systems more satisfying overall than any version of D&D (TSR, OSR, 3e, 5e, whatever). I guess I’m not a ‘rules lite’ person after all. In retrospect, I think that I thought that about myself only because I found running 3e D&D to be such a tedious chore. 

Of course, both Mythras and Against the Darkmaster are descendants of other ‘old school’ systems: Chaosium’s Basic Roleplaying (Runequest, Stormbringer, and the like) in the case of Mythras, and Iron Crown Enterprise’s Middle-earth Roleplaying (itself a simplified version of 2nd edition Rolemaster), in the case of Against the Darkmaster. So, I guess they're kind of ‘OSR’ systems as well (but not if we adhere to the “OSR = derived from TSR AD&D/D&D” definition). 

I can’t help but be struck by the extent to which my personal gaming history has repeated itself: dissatisfaction with AD&D/D&D led me to move to Middle-earth Roleplaying (MERP) and Basic Roleplaying (BRP), including Call of Cthulhu, Hawkmoon, and Stormbringer, in the mid-late 1980s. And about three decades later the same thing happened with OSR D&D and 5e D&D. Hopefully I've learned my lesson and won’t go through this cycle again.

As an aside, one thing that makes me think of the old MERP campaign modules as "old school" in nature is that – whatever their other faults – they were effectively “sandboxes” (as I explain here). They described a number of locations, some in detail, and provided advice for GMs on how to provide "hooks" for players. There were a few “adventure modules” for MERP – books with 3 adventures (usually aimed at levels, 1, 3, and 5) – but even those were pretty loose for the most part (generally they provided a setting and a situation), not “railroad” adventures. So, after my first several years with AD&D, a lot of my GMing involved using and running Middle-earth “sandbox” campaigns, although of course that term was not used in those days (at least to my knowledge). Indeed, I vividly recall comparing my MERP modules to TSR's Dragonlance series around 1986 or 1987, and noting how little room for improvisation or player freedom the latter allowed.

Anyhow, to the extent I was still involved in the hobby during the 1990s, the games I followed were those that came out earlier, especially MERP and Stormbringer (the latter revised and renamed Elric! during that decade). I remember visiting gaming stores in the 1990s and being a bit baffled and even put off by all the “goth” stuff. I never got into Vampire and the like (just as I never got into the Magic craze.) When D&D 3e came out, I was excited by it because it seemed to “improve” D&D by including certain things from other systems that I liked (e.g., skills). In play, though, I came to loathe the system after two year-long campaigns, and so was primed for the OSR when it happened.

Of course, had I been sensible, I would’ve just kept playing MERP, Call of Cthulhu, Stormbringer, and similar older games – and just ignored the hype around 3e D&D and the “d20” universe in the early 2000s. These days, for the most part, I’m happy to stick with my “d100” games, Mythras and Against the Darkmaster. Wisdom, I hope, comes with age.

My grievances concerning 5th edition Dungeons and Dragons: a final statement

Let me start with some background about what “fantasy” means to me and hence what I generally look for in fantasy role-playing games (FRPGs).

I saw The Lord of the Rings animated movie when I was 9 or 10 at a repertory theatre. Then I read The Hobbit. That got me really interested in fantasy stuff. It’s what motivated me to then ask my parents for the Dungeons and Dragons Basic Set for my birthday. (It was the one written by Dr. Holmes – hence it had those annoying chits instead of dice.)

As an adolescent I became interested in other works of fantasy – especially, in the early-mid 1980s, Michael Moorcock and Robert E. Howard (along with a lot of related pastiche “Conan” stories) – because of D&D and AD&D. The “Melnibonéan Mythos” in the Deitites and Demigods was one of my favourites in the book even before I read anything by Moorcock. 

 

Given these influences, I would say that Tolkien, Moorcock, and Howard had the most influence in shaping how I interpreted D&D/AD&D when I got into FRPGs in the early-mid 1980s. (I eventually would go on to play games directly based on the writings of Tolkien and Moorcock; indeed, these eventually supplanted AD&D in my high-school group.) Perhaps this is why – more than any particular set of rules – the more recent Wizards of the Coast versions of the game leave me cold. Over the past 25 years the game has felt more like “fantasy superheroes” than the kind of fiction that I had associated with it – and, I suppose, still do, when I think of “classic D&D.”

Turning to my experience running a “World of Greyhawk” campaign using the fifth edition rules – and leaving aside the game’s overall “ethos” and “aesthetics” (including its unfortunate recent turn towards “twee”) – there are three elements of the game that especially came to vex me:

a. Its “superhero” “no-wounds-are-serious” system of rest and recovery; 

b. Its “unmagical” magic system; and

c. Its flavourless, often tedious combat system.

(For further explanation of each of these points, go to the posts to which I’ve linked above.)

I recently managed to sell most of my WotC 5e D&D collection (I kept the core rules and a few books I liked, such as Saltmarsh and Yawning Portal). I used a local used bookstore for the sake of convenience. It felt good to free up the shelf space. I don't know why I bothered getting most of those books originally – even when I was playing 5e, I barely used most of them. (I stopped buying WotC stuff years ago when I realized this, as well as the declining quality of the line.)

I will say this for 5e D&D: it’s far better than 3e was. I mean, if 5e D&D were the only FRPG available, I would play it – whereas I would just abandon the hobby if 3e was the only option. And I would not rule out occasionally playing 5e D&D in the future (say, running a game for a friend’s kids or something like that). And I would be happy to play the Middle-earth variant, The Lord of the Rings RPG (indeed, I greatly enjoyed that game’s predecessor, Adventures in Middle-earth, having run a successful campaign about seven years ago).

But as for my “main” FRPG, I’ll never use 5e D&D again. Hence, I don’t have any interest in the new 2024 books. There are just too many superior alternatives (including, of course, earlier editions of D&D/AD&D, and related “retro-clones” and “near clones”).

Mournblade soon available in English

It’s been about a decade since the last official Elric-based roleplaying game went out of print in the English-speaking world: the excellent Elric of Melniboné (EoM) supplements written for Mongoose’s RuneQuest II (MRQII).

 

(More information about this line is available here. I had the good fortune to play in a MRQII EoM campaign with one of the line’s primary authors, Lawrence Whitaker; the first two-thirds of that campaign are described here. Since Mythras is a direct descendant of MRQII, it should be easy to use the EoM books with Mythras, should you be able to track them down. Tragically, the books are not available even in PDF anymore.)

 

In France, however, there is an Elric FRPG that has remained in print during this time: Mournblade from Le Département. (A brief overview is available here. Interestingly, Mournblade seems to draw quite a bit on Whitaker’s “flavour” work for EoM, that is, material on the history, cultures, etc., of the Young Kingdoms.)

 

I’ve long been intrigued by Mournblade and would’ve liked to read it. Alas, my Ontario high-school-mandated French proficiency has atrophied far too badly over the decades for such an endeavour to be viable.

 

Fortunately, an English version of the Mournblade “starter set” will soon be available in PDF as part of the Kickstarter campaign by Le Département for their boardgame Elric: Rise of the Young Kingdoms. You can “support” the KS for €10 and get the entire Mournblade set but nothing having to do with the boardgame. (This strikes me as quite odd, something I’ve never encountered before. But since I don’t want the boardgame—it looks beautiful, but I doubt I’d ever be able to play it—but I do want the FRPG starter set, I’m happy for this option.)

 

Here's what you get with the starter set (all digital):

 

• A 56-page rulebook containing core rules, a bit of sorcery, and equipment needed to fight in the Young Kingdoms.
• A 30-page quest book Dangerous Games. This quest is an introduction to the world of Mournbalde. While alternating between action and combat, players will be able to explore the fundamentals of the game.
• 6 pre-generated characters to choose from, including a sorcerer from Pan Tang, a brave Captain of the Purple Towns and a sellsword from Lormyr.
• An HD original map of the Young Kingdoms

 

Apparently the complete Mournblade line will be released in English eventually, so this is a relatively low-cost way to check out what the game is like.

 

Michael Moorcock’s “Eternal Champion” setting—especially the stories concerning Corum and Elric—remain one of my favourites, especially for role-playing campaigns. So I’ll be getting this Starter Set.

 

Blood and Souls for Arioch!

 

Fictional worlds and the RPGs that I would use for them

Below I list some of my favourite settings from fantasy fiction that I think could serve as viable RPG settings and the rules that I would use if I were to run adventures in them. 

Fictional setting: Middle-earth (as described by JRR Tolkien in The Hobbit, The Lord of the Rings, The Silmarillion, Unfinished Tales, and so forth).

 

System: Adventures in Middle-Earth (a 5^th edition D&D variant, heavily revised with ideas from The One Ring RPG) for the Third Age (I had a very positive experience using the system).

Possible alternative: Against the Darkmaster (VsD)—for earlier eras or if I'm drawing a lot on my old Middle-earth Roleplaying (MERP) collection, since it’s easy to convert MERP stats into VsD.

(Why not MERP? In my view, VsD keeps everything that is great about MERP and makes some helpful improvements.)

 

A further thought on Middle-earth: I'd like to try The One Ring (2^nd edition) system sometime—I have the book and box set, and they’re gorgeous. I played a couple of games of 1^st edition TOR years ago and didn’t care for it—something about it just didn’t “click” for me. But that may have been because I didn't really understand the system (or I was just too tired or something). AiME imports a lot of ideas from TOR, so there must be something there.

Fictional setting: The Elder Isles of Jack Vance’s Lyonesse trilogy.

 

System: The Lyonesse RPG (a version of Mythras).

One of my favourite FRPGs (Mythras) adapted specifically for one of my favourite fantasy settings—what more could I ask for?

(I think that this system also could be used for a “Cugel-level” Dying Earth campaign.)

 

Fictional setting: The Eternal Champion multiverse, including especially the worlds described in Michael Moorcock’s Elric (the “Young Kingdoms”) and Corum stories.

System: Mythras, especially with the (now out-of-print) RuneQuest II (MRQII) Elric supplements. Since Mythras is a direct descendant of MRQII, conversion would be a non-issue. (I played in an excellent Young Kingdoms campaign using MRQII a decade ago.)

 

Fictional settings: The Hyborian Age (as described in Robert E Howard’s Conan stories) and the Atlantean Age (as described in REH’s Kull tales).

 

System: Crypts and Things if I want something fast and furious; Mythras for detailed bone-crunching action.

 

Fictional settings: Clark Ashton Smith’s “Averoigne,” “Hyperborea,” and “Zothique.”

 

Systems: Again, either Crypts and Things or Mythras, depending on what style of game I want to run.

 

Fictional setting: The “First Law” world, as described in Joe Abercrombie’s original trilogy, and the post-trilogy stand-alone books (I think that the regions covered in Red Country and Best Served Cold would make excellent campaign settings). (Note: I haven’t read the “Age of Madness” trilogy yet.)

System: Either Mythras or Against the Darkmaster.  

 

Fictional setting: The “Cthulhu Mythos” universe (as described by HP Lovecraft and others).

 

System: Call of Cthulhu (naturally)—or possibly a modified version of Mythras (I'm playing in an excellent Mythras “Return to the Mountains of Madness” campaign now).

 

 

Mythras News: Supes and Polynesia

There’s a new member of the Mythras RPG family: the superhero role-playing game Destined. It’s available now at the Design Mechanism’s new home store, and will become available at Lulu and DrivethruRPG on the 23^rd of April.

 

Also, another Mythic Earth setting book is in production: Mythic Polynesia. I don’t know when it’ll be available, but the cover looks rather cool:

 

 

I’ve probably played more Mythras (including its predecessors RQ6 and MRQII) than any other role-playing game over the past eleven years. (By coincidence, I vaguely recall meeting Loz in early spring 2011…) I’ve played in the Young Kingdoms (Elric’s world), Mythic Britain, the Luther Arkwright multiverse, and (currently) Mythic Babylon. Soon I’ll be taking part in a Mountains of Madness campaign (converted to Mythras). I can’t recommend the game highly enough!

Steve Perrin, RIP

 

Influential game designer Steve Perrin passed away recently at the age of seventy-five.

In addition to RuneQuest, Perrin authored or contributed to numerous other role-playing games, including two of my all-time favourites: Stormbringer and Call of Cthulhu. And RQ's system, of course, informed all subsequent Basic Roleplaying (BRP, or “d100”) games. He also authored the influential AD&D module, Under Ilefarn, which was the first original adventure for TSR’s Forgotten Realms setting. 

Arguably, Perrin’s influence on RPG design was second only to that of the genre’s creators, Gary Gygax and Dave Arneson.

Shannon Appelcline provides a nice overview of Perrin’s work here.

Elric coming to the small screen?

According to Deadline we might see an Elric TV series someday:

“New Republic Pictures’ Brian Oliver and producer Bradley J. Fischer acquired the exclusive rights to all works in Michael Moorcock’s seminal fantasy-horror series The Elric Saga. They are beginning to shop the property for series, with Glen Mazzara (The Walking Dead and The Shield) and Prison Break and Star Trek: Discovery‘s Vaun Wilmott attached to adapt the sci-fi fantasy tale.” 

“Fischer and New Republic see the Elric saga — which begins with the 1972 novel Elric of Melniboné, as having cross-platform franchise potential. They are first leaning into the TV series with Mazzara & Wilmott. The novels are sensual and atmospheric sword-and-sorcery tales that center on the title character, a brooding albino warrior who presides over an unruly, decadent island nation. The novels follow Elric on a series of adventures, in which he is betrayed by his cousin, sent into exile and attempts to come to terms with his own humanity. The series comprises 11 novels and a number of short stories and has been adapted into several comics and graphic novels.”

While this wheel looks to be turning, the TV series (if it materializes) will not be happening in the near future.

In contrast, BBC Studios’ adaptation of the Runestaff tetralogy appears to be further along...

(Hat tip to C. Robichaud for the Elric news.)

My favourite role-playing games

Apropos of nothing, here is a list of my favourite role-playing games...





















Mythras (formerly RuneQuest 6 and Mongoose's RuneQuest II). 

This is the game that I've played (as opposed to GM'ed) the most in recent years. Highlights include: (a) playing a half-Melnibonean sorcerer in the Young Kingdoms (using MRQII) and (b) playing a Roman mystic-philosopher (in Mythic Britain). Among its many virtues, Mythras has (hands-down) the best combat system I’ve found in a RPG yet.



Call of Cthulhu. 

I've run a fair amount of this over the years, both campaigns and one-shots. It is probably my favourite game to run overall.



Classic Dungeons & Dragons (including Basic/Expert D&D, AD&D, and related 'retro-clones' [e.g., Swords & Wizardry, OSRIC] and 'pseudo-clones' [especially Crypts & Things]). 

I haven't played too much 'classic D&D' in recent years—except for a short AD&D campaign and a number of sessions of Crypts & Things (a game to which I contributed some rules)—but it remains a constant love for 30+ years.



Dungeons & Dragons 5th edition (especially as modified for Adventures in Middle-earth). 

Finally, an 'in-print' version of 'D&D' that I enjoy! I'm currently running an AiME campaign. It's a pretty solid realization of Middle-earth.




Elric! (a.k.a. Stormbringer). 

An old favourite (especially Elric!/SB5e). It’s a fantasy version of BRP (Basic Role-playing) that is easy to run and has a lot of flavour. While I think that the MRQII version of the setting (now out of print, alas) does a better job in realizing the Moorcock’s multiverse, I have fond memories of this game. 



Middle-earth Role-playing (MERP). 

I haven't played this game in years (the last time, I think, was 1999-2000), but I cherish my ICE collection of MERP adventures, campaign guides, and (especially) maps. Indeed, I am using some MERP material in my current AiME campaign. I ran my first 'real' (i.e., coherent) RPG campaign using MERP while in high-school, and still look back fondly on it. To this day I enjoy reading the critical charts.

There certainly are other games that I’ve played and enjoyed over the years (e.g., Traveller, Star Frontiers, Thieves’ Guild, DragonQuest, The One Ring, Trail of Cthulhu, etc.). But the ones listed above are the ones that stand out for me.
