uzz!: Quiz World is a portable entry in the long-running Buzz! quiz game series. It offers new features and 5,000 questions to play solo or with some friends. The solo mode is four times longer than before with four challenges instead of one. Players can also download official quiz packs through the PlayStation Store, or create and download custom packs by players (MyBUZZ!). Some of these are adapted from the PlayStation 3 version of the game. The multiplayer mode offers different ways to play with friends: a single PSP and a single copy of the game (Pass Around up to 6 players), a single copy of the game and multiple devices (Game Sharing), or multiple PSPs and multiple copies (regular wireless mode). A new feature is the online game through the PlayStation Network for up to four players. Also new this edition is profile creation. Players can choose a name for their avatar avatar from a long list of proposals. Host Buzz will then use that name to tease the player during the game.
