A rule system for computer RPGs
It may seem odd to write here about a rule system for computer RPGs, but really, it uses real dice and whatnot. You can play it tabletop just fine if you don't mind the crunch (there are ways to simplify combat). The important thing was making it not require the GM to be there and fudge dice rolls or make monsters weaker on the fly if the players are struggling, because computers can't do any of that, and notoriously struggle to handle rule systems designed for people to play among themselves, live around a (virtual) table. It also ended up having its own specific flavor, with rock-paper-scissors tactics and ways to beat the odds. All it lacks for now is a good magic system and a setting. Hope you find it fun and useful anyway.
