Inspired by yesterday's question - What game or game franchise do you feel deserves a sequel that hasn't had one in a long time (or ever)?

My choice would have to be Brütal Legend. As a metalhead, I absolutely adore this game but it did have it's flaws. I feel like a sequel could fix the flaws and refine the overall experience of the game. If all the various styles of gameplay were tied together more tightly with a better flow, Brütal Legend 2 would be an amazing game.
