At first touch, the PlayStation Move feels awfully familiar.
Unveiled at last week's Game Developers Conference in San Francisco, Sony's forthcoming wand-shaped motion controller and the smaller sub-controller handle similarly to Nintendo's Wii Remote and Nunchuck. There are differences, of course: It's lighter. There are fewer buttons. The batteries are rechargeable. And there's that big glowing sphere on the end.
The biggest difference seems to be in the games-admittedly in early stages of development-that were showcased for the PlayStation Move at several events during the conference. There's another level of interaction and kinetic fidelity with many of these titles because the system uses a PlayStation Eye camera and can literally make players part of the game.
