Video Game Movies (Is it Just a Matter of Time?)

When looking at comic book movies it seems that it just took a while for people to get them right but after a few attempts we eventually ended up with The Dark Knight and Avengers etc. Part of me thinks this is the eventual future of video game movies. I don't know all the movies in the works at the moment but I've heard that studios are working on some adaptations such as Mass Effect, Assassins Creed and The Last of Us. Those 3 games could make for some very interesting movies if done right, but who knows what will happen.

So what do you guys think? Is it just a matter of time or will it never happen?
