What game do you want a PC port of the most?

I've noticed that Steam has a lot of unexpected ports hit its storefront recently, and most of them are very late and very unexpected. Tales of Symphonia, Valkyria Chronicles, and Sonic Lost World come to mind, and with another one of this kind of port - this time for Vanquish - coming up, I've decided to ask what would be the game you would choose to be ported to PC. Unfortunately, first-party Nintendo exclusives don't count, because we want the ports to be at least a little plausible, but Playstation and Xbox exclusives are fair game.
