Oh come on. You know my play-as-RE-Zombie idea was totally Natal and totally hardcore. You could tear regular people's limbs off, make funny faces (which Natal would recognize and interpret as zombie faces for your character, which would be really cool in co-op), you name it.
Natal is a reverse-zombie-game dream control device. Imagine the funny gestures you (and co-op friends) can make while grabbing and gnawing on some victim's arm, or just trying to scare them, with some "scare the innocents" minigame. You can't claim that such a game wouldn't be *really* fun, and at the same time targetted at hardcore co-op play. I'm kind of making a joke with this, and kind of not. Natal will live or die based on the inventiveness of its game lineup. Point-and-click games, like those found on PCs, the Wii, and Sony's future motion controller, have been around for ages. Natal is new and different.
Capcom should seriously consider putting the fun in being a zombie, via Natal. ;) Resident Evil: Fun Under the Umbrella. I called it first.
