I take it you never played a Bioware game before. Graphics could have been better but it stayed in my 360 for months. Gotta go back and play with my 4 characters on the hardest difficulty just to get ready for the second one. To each his own I guess.
No doubt, I played the SHIT out of Mass Effect, the only complaint I have about the game is the fact that the side quest could have been done a lot better. Aside from that I beat the game at least 4 times.
I'm putting off my final Insanity/last 2 ally playthrough until just before part 2 comes out.
