Okay, this is late but now that I've played DE:HR I can really sort of comment on this. The Wii U controller stuff looks nifty although I wouldn't go out and buy a Wii U just for that. Energy cell rebalancing needed to happen. I would pay money for that... in a PC version.
Play the original Deus Ex broski. I beat the game without killing anyone. (Except for Navarre's kill phrase, I guess, but that doesn't count.)
