My two roommates are big gamers and I have talked with them a lot of this game. (They actually might show up in Y3/Y4). But I said, "So if Mass Effect was made into a movie should it be PG-13 or R?" My roommates said, "Definitely R if they want to pull in fans and gamers, but PG-13 if they want the money." I always with my films pull toward faithfulness than the cash. But again, if anybody can pull off a film, it can be you.
