In addition to Sports Champions (which, let's be honest, may as well be called "PS3 Sports," but you can't blame Sony for following the money), Sony also announced a slew of other games that'll use the PlayStation Move motion controller, including Move Party, Little Big Planet, EyePet, Motion Fighters, and the recently revealed SOCOM 4.
First up was Move Party, which seems to be an amalgam of random mini-games with a bit of a WarioWare vibe, but also the "augmented reality" style of games the PlayStation Eye (and EyeToy on the PS2) often featured. It shows the player on the screen in each mini-game, but with the Move controller replaced by what each mini-game requires. The demonstration included mini-games where the Move controller was used to swat bugs with a tennis racket, color in shapes as though it was a paintbrush, or, uh, cut someone's hair as though the controller was an electric clipper. Again, it was all very fast-paced in a WarioWare style.
