World Of Gainar Fantasy Role Playing System
The World Of Gainar is a massive work — a complete RPG system set in a post-apocalypse fantasy world. This is no Gamma World, however.

For those who just want the background, there’s a stripped down version that’s just the world book.
Warrior and Wizard RPG and Combat Game
Warrior and Wizard is an RPG and Combat game apparently inspired by The Fantasy Trip.
