A Mass Effect Movie?

Mass Effect, for many Xbox fans including myself the best game on the 360 will propalby get an movie adaption as 1Up reports:

Variety's The Cut Scene blog reports that "numerous sources" have confirmed that Avi Arad has optioned the movie rights to BioWare's planet-hopping RPG, Mass Effect.
[...]
Neither BioWare-owner Electronic Arts nor Arad provided a comment to Variety, but writer Ben Fritz speculates that Arad is most likely already at work bringing a writer, director, and studio together for the project. No word on when it could potentially be released, but it likely won't be for at least a couple of years.

Okay, let's hope this won't happen. Mass Effect is a genuine experience that lives from the freedom of choice and needed lots of time to tell it's story. (My playthroughs were 25 and 30 hours.) It felt natural as videogame and I think it should stay that way.
Sure, there are exampels of better game to movie adaptions like Silent Hill. But even with these it can't be denied that they in no way top the games on which they base. I don't understand why most people see movies as superior to games. That's like saying watching TV rules over the internet. TV and film are one way streets - games and the net are rich in complexity. But that adaption thing is nothing new, right? Started decades ago with the novel picturization. At least it brings new audiences in.
