The Wildside Gaming System: Fantasy Roleplaying Edition
This is the heroic fantasy version of a roleplaying system that I've been playing and tweaking for years. The system works as a simulation in other environments as well; I've run it in a far-future environment as well as doing Roman and other historical versions, but most people seem to like the fantasy version best. The Wildsidegame website has samples and a bunch of free downloads for current players, as well as order links.
