ANTIMATTER: A Cosmically-Balanced RPG
A downloadable tabletop rpg
The cosmos can be a brutal and unforgiving place. Take what you can and hope that the karmic backlash ain't too much to fret over.
Welcome to an interplanetary sci-fi setting where morally-flexible space rogues take on a variety of legal, extralegal, and illegal jobs. When the authorities can't catch you, karma might. The galactic scales will eventually balance out and no one can keep flying forever.

Antimatter is a rules-light role-playing game where characters don't have successes and failures. They have successes and antisuccesses. But just as the creation of matter results in antimatter, successes beget antisuccesses and vice-versa.
What Does That Mean?
A pool of outstanding successes and antisuccesses builds up throughout a mission. When a player gains a success, an antisuccess is added to the pool, and vice versa. Once the mission is complete, successes in the pool are resolved as post-mission positive effects (gaining a new ally, for instance). Antisuccesses in the pool are resolved as post-mission negative effects (losing the money gained along the way, for instance).
The Core Mechanic
Antimatter uses one of two resolution systems. If a character is good at something, they simply decide whether the result of a check is a success or antisuccess. When they aren't good at something, the flip of a coin decides the results.
Here's what a character might look like...
