I could go for some Mass Effect: Wing Commander (with an optional "realistic flight sim" mechanic for the GB Flight Club). Hell, Wing Commander III and IV remind me of Mass Effect in so many ways. (And let's not forget that a certain voice actor had previous experience with the franchise)
Street Fighter II: Hyper Fighting --> Street Fighter II Turbo: Hyper Fighting (and rename to Street Fighter II': Hyper Fighting) This is kind of debatable. Street Fighter II Turbo: Hyper Fighting (SNES) is a port of Street Fighter II': Hyper Fighting (Arcade, known in Japan as Street Fighter II' Turbo), adding an optional mode to make it resemble Street Fighter II': Champion Edition. I'm not sure this makes it a legit article (since it's pretty much a port). Agree/disagree?
Plus, SF2T:HF has achievements for the XBLA version of SF2':HF.
