Red Dwarf
In early 2004 I was briefly enthralled by the Red Dwarf RPG, a sci-fi comedy game based on the much better-known British sitcom of the same name. For my own amusement, I created characters, one each of the various types described in the rulebook.
Separately, I wrote up Fry (the protagonist of Futurama) as a Red Dwarf RPG character, which was harder than it sounds.
