Worldbreaker is a game I invented, inspired by
what I had read of
Universalis before I actually got a copy of the
game. It's much,
much rules-lighter than
Universalis, but
it's meant for creating
settings, not story. And it works
surprisingly well.
The rule (yes, singular) can be found
on my personal website;
here are some actual play results for you to enjoy, including the first
game, which gave the game itself its name.
