What is Microlite20

Do you remember when the gaming table was full of pizza and soda, not rulebooks, miniatures and dungeon tiles? Do you yearn for a role-playing game that doesn’t require weight training to carry all the books? Do you want to be able to hold all the rules in your head - or in your back pocket? And do you still want to use all those lovely monsters, adventures and game worlds too?
So do we!!

Rules light d20 gaming

Microlite20 (M20) is based on the popular d20 Role Playing Game (RPG), but with more of a focus on brevity. Unlike the massive Tomes of rules clocking in the hundreds of pages realm for just the core rules to play, M20 is well under 50 pages.

The philosophy behind M20's design is that the minimum necessary complexity should be created to capture the desired feel. By doing this the game is super easy to pick up and play, but also incredibly easy to tweak to your group's needs!

Who is M20 good for

While M20 has something to offer everyone, there are a handful of groups that really benefit from the microlite philosophy of gaming.


Professionals, students and parents all can benefit from the lightweight presentation of M20. While other games can feel like you're playing Rulefinder, busy people can waste less of their time learning how to play and more time doing it.


One of the key benefits to M20 is its lack of moving parts. While other games with more rules have far more game balance concerns to consider with even minor adjustments, M20 is small enough that you can easily grasp what effect changes you make have.

This is certainly been proven by the more than 100 fan made rules and variants of M20 to date.


The vastness of your traditional RPG can be pretty intimidating to new gamers. We know that and so everything we are doing is focused with that in mind. From the Rules Cyclopedia to stand alone books, you can be confident that the content and community will be there to guide you.

Where to start

It's no doubt that there is a lot of content that the community has created massive amounts of material: and that’s awesome. At the same time, it can be a little daunting for people to know where to start, that’s why we're here!

Rules Cyclopedia

This is a fantastic starting place for new comers and old timers alike.

For those brand new to things the first section of the book covers your needs. You get a fully playable game, and the fundamentals that all the other community modifications build on.

Even if you're not new to gaming or M20, skimming through all the awesome alternate rules can help you put the perfect game together. 

Stand Alone Setting Guides

We are also putting together a handful of pre-packaged rules that are perfectly suited for certain types of game styles. At this time we are putting together the first of our Setting Guides with the input of the community and our patrons.
