Now I am pretty torn. I will probably get either the 360 or pc versions because of the mass effect item. I was leaning pc version because, honestly, the community stuff would be awesome for this game, but that that would lock me into getting mass effect 2 on pc as well. I was planning on getting mass effect for my 360 because I think it fits better on a console. I just don't know what I'm going to get anymore...
