Faith Fighter is a fighting game with seven characters, all of them major religious figures: Jesus, God, Mohammad, Ganesha, Buddha, and the Laughing Buddha, and one secret character. I like a lot of the details the game has (like the Flying Spaghetti Monster appearing occasionally in the background and so on).

(As an aside, one of my friends and I once had an idea for a slightly similar game -- maybe we'll make it one day.)
