Colony Ship: A Post-Earth Role Playing Game

Colony Ship is an isometric, party-based RPG inspired by Heinlein’s Orphans of the Sky. Your character's world is a “generation ship,” a massive spacecraft on a centuries long voyage to colonize a distant planet. The Ship's original government has been disbanded following a violent mutiny and you must negotiate a treacherous path among your fellow passengers and the contentious factions striving to dominate the Ship. Your choices alone will determine who your friends and enemies are. (Mobygames)
