I could contend that games and movies run sort of parallel to each other. Swerving into the others' lane is generally a bad idea because your moniker is far better than you'll ever be.
Sure Prince of Persia's doing alright in the box office. But given time are people going to remember the game series or Gyllenhaal's rendition?
You essentially have 2 kinds of games. The Plot Heavy games and the Plot Light games. Halo and Modern Warfare are Light in that they sell games based on gameplay, not story. Making a movie would require writing a decent story and just tossing in elements from the game to let us know it's legit. Making a movie of a Plot Heavy game is going to end badly either way too; whether you try to retell the story in a different light, or if you just copy the story verbatim.
