I learned role playing in 1st edition D&D.
I have been working, for 6 years, on Epic Power, a role playing rule system that minimizes arbitrary details, maximizes player and GM flexibility, and is still crunchy. After lots of play testing and revising over that time, it is now open to beta testers, module included.
