For the first installment of GM Tips, I’d like to take a good look at what possibly is one of the most important decisions you’ll have to make as a Game Master: What game are you planning on running?
What I have prepared here is a selection of D20 Fantasy RPGs that are my personal favorites, balanced to provide a glimpse of what’s widely available in the market and to provide options that are great choices for beginning Game Masters to run at the game table.
As a note, while there are a number of other game systems out there that are great and beginner friendly (games such as Dungeon World and FATE come to mind), I’ve chosen to focus on what is usually the first experience many beginning GMs have running – D20 games based off of traditional D&D, where the 20 sided die is the most commonly used dice mechanic. I will cover such other games at a later date in a different article.
That said, here is my list of go-to games when I am running RPG campaigns for first-time players.

Basic Fantasy RPG
BFRPG is my all-time favorite game of choice when playing with not only beginning players, but veteran role players as well – as the game is simplistic enough for beginners to understand quickly, but is versatile enough to handle just about any scenario or situation that could occur in roleplay with the GM’s imagination and creativity.
Basic Fantasy RPG is one of many OSR (short for “Old-School Renaissance”) games that are widely available, which all seek to emulate the rules of earlier editions of the world’s greatest fantasy role-playing game while “cleaning up” those rulesets in order to make them more easily utilized at the game table. In particular, BFRPG is written in the vein of the 1981 Basic D&D boxset, but has a number of changes in the rules that I find make it very easy to run the game for all sorts of players.
In comparison to the before-mentioned earlier editions of D&D and similar games on the market (such as Labyrinth Lord, which also has a place on this list), the main change in BFRPG is that the game uses Ascending AC (Armor Class), instead of the Descending AC of those earlier games and retro-clones.
This change alone makes it much easier for beginning players to grasp, especially those who may have already played games such as Pathfinder or D&D 4e and 5e which all use the same mechanic for how Armor Class is handled. This allows for players to quickly convert over to playing BFRPG after having played other games without having to relearn how to handle combat. Another important change is that unlike the box set BFRPG is based on, races and classes are independent of one another – so a player could chose to play as an Elf Cleric for example, something that may not be possible under other OSR rulesets.
Outside of those changes, my main love for BFRPG is due to the fact of it’s simplicity – rules language is very concise and to the point, and is very open for Game Masters to house-rule and edit as they please in order to better serve the needs of their players. During play, the nature of these rules (to be fair, this is true of most OSR games) tends for them to fade into the background so that the GM is able to focus more on the narrative and plot of the game, only being really needed to be consulted when checking for specific mechanics such as Thief Skills or Saving Throws. This opens much time for the GM to really immerse players into the world of their setting and actual play, verses spending crucial game time consulting the rulebook for a multitude of situational rules that may hinder other systems.
While there are some things that beginning GMs and Players alike may find “wonky” at first (such as previously mentioned Thief Skills or Saving Throws), these concerns are quickly overcome and become second nature with even a few sessions of experience playing the game, or can be quickly house-ruled to your liking. (One such house rule of mine is to do away with “Prime Requisites” completely, so even if a player did not roll high enough ability scores to play a Paladin or another class they wish to play under the rules as written, they could choose to do so anyways in my campaigns.)
Another strong benefit that BFRPG has is it’s extremely strong community presence – there is a multitude of additional rules, classes, monsters, treasure, adventure modules, and other such supplemental material that can be downloaded or printed off from the main website, and a forum which many fans have provided even more additional material that can be used with the core game as the Game Master sees fit.
Maybe the best benefit of all is that the game is completely free – all of this material is available for download or print on the BFRPG website, though there are POD rulebooks if you desire.
I’d also like to give a shoutout to Chris Gonnerman for being such an excellent sport when it comes to the game he wrote – if you have a question, he’s usually more that likely going to give you his rulings and insight on how he wrote particular rules as he did, and frequently replies on the forum and elsewhere.
With that, please do check out Basic Fantasy RPG, as it’s one of the best games out there in my opinion.

Labyrinth Lord
While Basic Fantasy RPG has mechanical changes that are very friendly to first time modern players checking out traditional gameplay, Labyrinth Lord is a similar game but sticks to it’s traditional influences.
In comparison to BFRPG, Labyrinth Lord uses traditional Descending AC which may throw off modern players – but in reality it is easy to figure out and most character sheets will have a nice “To Hit Target AC” chart that will allow you to quickly determine how a character fares in the middle of a combat encounter.
Also, Labyrinth Lord’s core game (Classic Edition) sticks to the tradition of demihuman races (Elf, Dwarf, Halfing) as being their own separate class altogether in comparison to humans, which could choose to be Fighters, Thieves, Clerics, or Magic Users. As such, you wouldn’t see a Elf Cleric character – you would just see an Elf.
However, Labyrinth Lord has additional rulebooks such as the “Advanced Companion” which models after 1e D&D rules, or it’s “Original Edition Characters” which models after the very first original D&D ruleset – so you can mix and match to get the rules you want – you could have a Elf character built with the Classic Edition rules fighting alongside an Elf Fighter built with the Advanced Companion rules, for example.
Lately I’ve been running a LL campaign using the Classic Edition and the Advanced Companion book, and it’s been my poison of choice – quite like BFRPG it is frankly a well done rendition of the various rulesets of the past, and pars down quite a bit of the rules language so it is easy to comprehend for most players and easy to run at the game table. Even while doing so, it keeps enough of these rules that it plays very much like it’s source material – and it’s great fun.
One thing I should note when it comes to OSR games such as BFRPG and LL, however, is that you will notice that mechanically most characters are pretty lean in comparison to modern RPGs. Outside of a few key abilities or achievements gained at certain levels, most classes will have “dead levels” where the only thing gained for the character is additional HP. While some players or GMs may not like this, I personally love the mechanical freedom of such games – as it allows you to focus on the story of what characters accomplish in the narrative of the campaign.
Another note is that OSR games tend to be rather deadly to characters as well – there is a higher focus on surviving encounters in any way possible other than fighting, with lesser XP awards granted after defeating monsters in combat, so there are many times when it is preferable to avoid combat than engage in a fight that could end up in the death of a character.
Of course, much could be said about the differences between those original game rulesets and their retro-clones in comparison to modern RPGs, but that’s another discussion for another time.
Regardless, Labyrinth Lord is fantastic for those looking for a game that faithfully emulates the play of older D20 Fantasy RPGs, and I highly recommend it as well.
You can find downloadable art-free copies of the Classic Edition and Advanced Edition Companion rules at the Goblinoid Games website, which is another major plus. Feel free to try it out – I’m pretty sure you’ll enjoy it.

Dungeons & Dragons 5th Edition
As you can tell, I do very much love the original rulesets of this game in particular, and I tend to run OSR retroclones of those rulesets when I get the chance.
That said, far and away I think that of the published D&D editions since Wizards of the Coast took over from TSR (3e, 3.5e, 4e, 5e), 5th Edition D&D is the greatest rendition of the game currently available.
Overall, it feels like a continuation of 2eAD&D, having taken design decisions from the earlier 3e and 4e games and blending them together to make a really streamlined yet mechanically robust game that is an absolute pleasure to run at the game table.
For the beginning GM, 5e is a great choice to begin learning how to run RPGs with – as the mechanics are simple enough for people to grasp (with some incredible mechanics such as Ability Scores being tied to Saving Throws, or the Advantage/Disadvantage rules, which really clear up alot of the clutter in previous D&D editions), but versatile enough that a GM can houserule specific rules as needed without severely hindering other parts of the game ruleset.
Characters and their options are really robust as well – with multiple options for how a character could gain new abilities depending on their class, the optional background rules which really help new players figure out the kind of character they want to play, and all sorts of other additional content such as the feats. However, the great thing about all of these options is that they’re mechanically very simple – and very effective at changing the mechanics of the core characters, so it is easy for players to build characters they want to play in your campaigns.
It’s really easy to create dungeons and encounters with 5e, and there is a number of options in 5e to make combat either more dangerous or survivable for player characters – so it’s readily editable enough for the Game Master to really make a campaign run in the way he or she wants to.
Finally, 5e benefits from an already enormous wealth of additional content available, so it is very easy to add additional classes, races, spells, and all other sorts of content into your games. It seems that 5e will receive support for a good long time so I’m sure that this trend with continue – and in the event you find material from earlier games you want to play, it’s easy to convert that material over in order to play it with 5e rules.
The Basic Rules for 5e are readily available here:

Pathfinder
Pathfinder is an evolution of the 3.0 and 3.5 D&D rules, but benefits from the fact that as Paizo continues to develop content for it’s game that it will be supported for a very long time to come. It’s an industry standard, and for very good reason.
One thing you will notice in Pathfinder (and the earlier D&D 3.0 and 3.5 by association) that there is an almost unlimited amount of character creation options available to players. A common saying is that “If there’s any kind of character you want to make, you can make it in Pathfinder”, and that’s definitely true. There’s so much additional content available for Pathfinder out already and planned in the future that you can build a campaign setting just the way you’d want to run it, which is a huge benefit to the game.
I would recommend that first time GMs try running something along the lines of 5e or an OSR retroclone for their first campaigns, however – as there is a large amount of rules in Pathfinder that may be confusing at a first glance without prior experience.
However, regardless of that, GMs and players who want a very comprehensive and expansive set of rules that assist in the running of their campaigns and characters will benefit greatly by choosing to run Pathfinder – as the content out there can readily assist them in running exactly the type of campaign they want to.
Paizo maintains the PRD (Pathfinder Reference Document), which gives you a good portion of the rules and content they’ve released thus far.

Dungeons & Dragons 4e (And Dungeons & Dragons 4e Essentials)
This is probably going to be a very contentious choice on this list for most veteran Game Masters and players I know, but for the sake of my personal tastes I will include 4e on this list.
To be frank, 4th Edition D&D is still the most divisive edition of the game that was ever released – and plays like it’s own game to be completely honest. Many changes were made in how 4e is played in comparison to 3e and prior editions of D&D, and the later 5th Edition (as mentioned above) used only portions of 4e in it’s blending of all prior rulesets in how it is ran.
However – I can say for a fact that 4e was a great system to learn the basics of roleplaying on, as 8 years ago 4e was the game that I first learned how to run RPGs with. While I much prefer OSR clones and the other two choices on this list these days, 4e is still a decent game for beginning players.
One of those reasons is due to what some consider an overwhelming focus on combat tactics – as a video gamer that absolutely loves tactics VRPGS such as Fire Emblem, Shining Force, or the original X-Com games, 4e helped me transition really quickly to running RPG sessions at the tabletop, as the combat is very familiar to those who enjoy such video games.
Along that thought, 4e did streamline a number of rules in comparison to 3e and the ruleset is presented pretty well – it’s easy enough to make a character or to build a campaign setting under the 4e rules, and quite like 3e there is a widely available amount of additional content for players and GMs alike in the system, covering all sorts of additional classes and other options.
I will say that personally I did have to do quite a bit of houseruling 4e in order to get it to run the way I wanted it to. One of the chief complaints of how 4e runs is how long combat can get under the rules as written – which after editing things like monster HP math and other such details of the system, I found that this was easily enough addressed and enjoyed the ruleset for what it was. In regards to building characters, it’s a very robust system in the vein of 3e so it’s easy to build the kind of character you’d like to play.
A good thing now that the game is no longer supported is that the various rulebooks are now available for rather cheap – so it’s a good starting point as well, and for enterprising Game Masters this is a good system to learn the basics of houseruling and learning when houserules are appropriate.

Now, by no means was this an exhaustive and end-all list of D20 based Fantasy RPGs – this is just a list of games I tend to run to help others get into the hobby.
There’s a number of other games out there (and of course, there are the classics such as 1e and 2e Advanced Dungeons & Dragons, but I do find that retroclones are usually preferable to run for beginning players) – so if you find something you like, go ahead and run it!
There’s no such thing as a “bad” ruleset for running games, as for the most part you can readily houserule these games to run them the way you would like to. In future articles I plan to look at some of these games in further detail, showing you how to do just that.
For further reading, if you are seriously interested in becoming a Game Master I recommend you definitely read the PHB (Player’s Handbook) and DMG (Dungeon Master’s Guide) for 1st Edition Advanced Dungeons & Dragons, as those two books are a treasure trove of information for the hobby in general, and many things that Gygax wrote in those two books is applicable across the whole spectrum of tabletop role-playing games.
In the meantime, if I missed a game you consider a great entry point into the hobby, let me know! I’d be glad to look it over and definitely recommend them as well.
