I'm part of a small little company consisting of me and myself. There isn't on our own website, but it does include the game system in development for the past few years and a couple pages worth of house rules. As a diversion from play-testing our game system, I started up a small Exalted campaign in an alternative universe, loosely based on the Earthsea and White Wolf's own rules.
The latest change that we made was to create a variant of the World of Darkness combat system introduced during GenCon 2004. It uses only a single roll to attack instead of an attack and damage roll.
