NeRP (New Role Play, a title I regret making so close to GURPS) is a tabletop RPG system designed by myself to capture the depth and possibilties of 3rd edition D&D, while staying away from the complexity that tied it down. It focuses on elegance, having fewer rules with more ways to apply them, instead of lots and lots of exceptions and special rules that only come up once.
The ruleset can be found here. There is also a demo to serve as a more narrative introduction to how the game works.
