The problem with video games being turned into movies is that they're already based on movies that were already made. Metal Gear = Die Hard, Tomb Raider = Indiana Jones and DOOM = Aliens. So unless they try to innovate the story and not just change it for infringement sake, its all stuff that we've seen before, except this time it's crappy.
The one franchise I was hoping to turn out as good original movies is the Final Fantasy series and they f'd that up twice already.
