ugh, why is it that whenever a game series hits another system, it is going to be negatively impacted? This thread is just damage control, trying to negate the value of the game to ps3 owners and condemn the developer for opting out of exclusivity.
Fact of the matter is this is a good thing. More sells means more effort will be given to subsequent sequels. Mass Effect should be more than a 2 mil selling game, it is better than that, and I for one am excited for ps3 owners to have a chance to play it.
Honestly, I don't think it is all that necessary to play the first game anyway, the second game does a good job of breaking you into the story, and each game is pretty self contained, which is awesome. I hate games that don't actually end (like halo 2 or WKC)
