Paul Reiche III is an American game designer. His career started in the pen and paper RPG industry, where he collaborated with artist Erol Otus on games such as Dungeons & Dragons and Gamma World. He then transitioned into video games, working with Jon Freeman to establish Free Fall Associates and developed titles like Mail Order Monsters, World Tour Golf, and Archon. Later, he left Free Fall to establish Toys for Bob with Fred Ford. Their first collaboration resulted in Star Control. After a successful sequel, they declined to make a third installment, instead focusing on other projects including the successful Skylanders franchise.

Gamma World is a post-apocalyptic science fantasy role-playing game in which player characters explore Earth centuries after the collapse of civilization, searching for artifacts from the time before "The Great Upheaval". The game was originally designed by James M. Ward and Gary Jaquet, and first published by TSR in 1978. It borrows heavily from Ward's earlier role-playing game, Metamorphosis Alpha.
