The games that should be made into films need to have an easily understood and adapted storyline that is unique (more or less) to that game. The Legend of Zelda works, but it's unwise to expect Ocarina of Time. As such, games like Final Fantasy 7 shouldn't be made into a movie.
Furthermore, we've already had many Batman movies, so Arkham Asylum is unneccessary, and with the dozens of crime dramas, westerns and war movies we already have, there is nothing special about GTA, Red Dead Redemption or the Call of Duty series, and they're not necessary to make movies for.
Resident Evil is a tricky one. Yes, they were made into movies, and honestly, the way they were done is really the only way to do it where the movies will stand out, otherwise, what will separate Resident Evil from Dawn of the Dead or the countless other zombie movies out there?
Rocketman has the right idea. Find a game that has a good concept and make a movie based on it. Don't expect a direct adaption, especially on games in extensive series.
