Mass Effect is my favorite game for the 360. I played through it like 5 times and got most of the achievements. I'm just glad its a trilogy and that theres going to be 2 more games to it. The gameplay can only get better from here on out.
the ally achievements are still a bitch im working on the specialist ones now OH and i just beat it on hardcore and gonna do insanity soon OH OH and i hit lvl 60 =D
