OK RPG
OK RPG! is a lightweight roleplaying game engine that is designed to be free¸ simple¸ complete¸ and beginner-friendly. It's a printable pamphlet that you can make a bunch of copies of to drop wherever you want. The format¸ color¸ and design choices are designed for maximum spreadability. The game is ludicrously simple to read¸ play¸ and run; the text is under a thousand words¸ and the language is appropriate for elementary school kids. There's essentially zero math or rule memorization needed. It's a complete game; it explains play from the very beginning with no assumed experience with RPGs¸ and the rules are designed to cover any situation that might arise during play¸ with no need for house rules or guessing. It's lightweight enough to get a one-shot going in 5 minutes¸ but robust enough to support long campaigns.
