Onepagerules Wiki
Welcome to the OPR Community Wiki!

OPR (onepagerules) is the home of many single-page rulesets designed to be fast to learn and easy to play, most known for the Grimdark Future and Age of Fantasy series of games.

The website features alternate rulesets to be played with any miniatures you have available, and they were written by Gaetano Ferrara (aka onepageanon) since 2014.

The mission statement is to create rules that everyone can enjoy, and to 'leave no man behind' by providing systems in which players can use any and all of their miniatures instead of having to leave them on a shelf to collect dust forever.

Since 2017 the project is being funded via Patreon:
