Of the "brand name" RPGs, my favorite is Savage Worlds. However, I built my own system that fits somewhere between d20 and Savage Worlds on the Rules Lite/Heavy spectrum. It fits the feel that I am looking for in a typical game. It is realistic enough to keep me grounded yet fictional and cinematic enough for action-hero pulp games.
I'm looking for reviewers/play-testers if you are interested, PM me.
