Have you ever played the grand father to the FPS genre, Wolfenstein 3D? I've played the 360 version of the game, I just need to get one more achievement then I'll have them all. I beat the game on the second hardest difficulty, but I need to beat it on the hardest. I haven't played any of the other games in the series though. I know the first Wolfenstein game was a platformer. :V I like it but not as much as Doom.
