This one will predictably fail as they all do.
Video games by and large have dull plots. The fun is that you get to play it. A movie of this will result in little more than a video walkthough.
If you make a movie out of ME, it will be obvious that it's just Bablyon 5 (Citadel, alien politics) meets BSG (bad robots). And in the movie there won't be exploring the world, making decisions, upgrading you character or choosing your party. Swell!
