Quick update: there seems to be Cosmic Patrol hack that takes place in Futurama’s world. For any fan of the tv series this might be an interesting game.
You can get it here.
For everyone who, like Bucyrus, doesn’t think that Cosmic Patrol is a good game, there’s Futurama’s variation using Toon RPG’s rules – much simpler, but also fun.
It can be downloaded from here.
