Sonys Start the Party! is a collection of whole-body mini-games that can be played alone or with a group. It is one of the first retail releases to use the PlayStation Move motion control add-on system. Players slash, swing, jab, and swat with their PlayStation Move Navigation Controllers, to trace and paint onscreen shapes, bat away at buzzing bugs, give super-fast haircuts to a bushy-headed character, smack open a piñata, pop floating soap bubbles, and perform other action challenges. More than 20 different activities are featured. Through the PlayStation Eye camera -- part of the motion-control accessory system -- the game puts images of the players in the game screen, so they can watch themselves in action.
