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 rules of M20. While other games can feel like you’re playing Rulefinder, M20 lets you waste less 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.



The vastness of your traditional RPG can be pretty intimidating to new gamers. 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.
