I know there's no hope of this actually happening, but I'd be thrilled to see the whole concept of video game movies just go away--and not only because all such movies have invariably sucked. What do we gain by compressing a twenty-to-thirty-hour game into a two-hour non-interactive unskippable cutscene?
Making a movie out of a game arguably could have been justified fifteen or twenty years ago--actual human beings, after all, are easier to empathize with than a blocky, vaguely person-shaped pile of pixels--but the march of technology has pretty much solved that problem. Most modern games look just as good as any movie. There have been many games that do a better job of telling a story than a movie could have: I'd dare say that the Mass Effect series beats the shit out of Star Wars (the last ten minutes of ME3 notwithstanding).
What's more, games, by design, are interactive. Movies are not. When you're playing a game (assuming the game was made correctly), you're literally part of the story. But movies? You're just sitting there, watching. I see no point in taking an interactive experience and removing the interactivity.
Really, video game movies don't appear to benefit anybody but the studios making them. They make movies out of games for the same reason they make movies out of TV shows and books and comics and commercials and theme park rides and children's toys: because they're looking to make a buck on name recognition alone. (And the studios can't even do that right, given the tendency of video game movies, as previously mentioned, to suck and fail.)
