After the promise of Mass Effect, Bioware decided it was time to really flex some muscle. This game is one of the best sequels ever made. I know the ammo changes are controversial for some, but I think this game did just about everything right as a follow-up to the first. It expanded the universe, brought in great new and old characters, and offered more interesting missions that deepened the personal relationships that made the first game so great. The one big knock I have against it is personal, and it relates to one of the companions who doesn't get as much playtime as the others. Otherwise, a game with few flaws.
