Riverworld by Steve Jackson Games

Enter the Riverworld, where every human being, from ancient primitives to future astronauts, is reborn along a colossal river stretching millions of miles. The river's end holds the universe's ultimate secret and the key to eternal life. GURPS Riverworld brings Philip José Farmer's series to life, allowing you to play as anyone from history, or even yourself. Interact with diverse historical figures, recreate technology, form societies, build riverboats and airships, and journey to the Polar Sea and the Dark Tower of the Ethicals.
