Equa! is an OSR adjacent system for tabletop role playing. It is about as minimal and esoteric as a role playing game can get.
The system itself is presented as a set of 'equations' that are only as correct as need be to facilitate the playing of the game.
Make of it what you will.
Equa! and it's expansions and addons follow a similar ethos. While not all being laid out as equations they all provide you with the tools to do something while leaving how to use those tools up to the players.
