I have played through mass effect 2 times on the xbox360 and I must say its the best RPG I have ever played, easly a 50+ hour game when your a completionist. check this link out sbrehm. http://media.xbox360.ign.com/media/718/718963/vids_1.html watch some of the dialog scenes on page 2 the video is called Elcor Conversation. it's truely a glimpse of what the future holds for games in terms of interaction with NPC's. If your not a big rpg fan you might have different feelings about this game.
