Sadly, Mizuguchi-san wasn't done talking yet. At the end of his presentation, he made a Freudian slip, one that I wont soon forget. I believe his exact words were, "Playing the game with Kinect is very difficult... I mean... different. It is very different." He was actually wrong both times. The word he should have used was "broken."
Kinect effectively ruined my experience with Child of Eden. It was a great idea in theory -- play a shooter where you aim with your hands, change weapons by clapping, and launch bombs by stretching both arms in the air. I would have loved that. It could have been total body immersion into the game world. What I got instead was a total backfire. As it turns out, it was poorly implemented, full body-only work that made the player constantly aware of their body and the frustrated in their attempts to interact with the game world. It's the opposite of immersion. I'm still definitely going to buy Child of Eden, but I'll be using the standard analog pad controls, or maybe the PS Move control scheme, assuming they aren't also broken. Unless there are some serious changes prior to release, I wont be touching the game's Kinect controls with a ten-foot pole.
So yeah, score one for Child of Eden, but strike one for Kinect.
