When Deus Ex: Human Revolution launches, two things are going to happen: 1) People are going to inevitably compare it to Mass Effect 2 and 2) Fans of the original game are going to find a prequel that carefully and methodically takes its cues from Warren Spector's masterpiece. I know it's not actually out and I didn't get to toy around with the final product, but my near three hours playing through the beginning of the game and its first major mission were incredibly telling of what Eidos Montreal is trying to accomplish here. This is going to be a special game.
