I can appreciate someone's love of obscure sci fi and enthusiasm, but come on. That was one of the worst movies of all time. I feel more retarded just thinking about that abortion of a movie.
On a more serious note, what elements from the movie would you incorporate into an existing game, like Traveller for instance. Maybe an article on a worker class and a few vehicles might be more apporpriate, along with some NPCs and new adversaries.
