While the PS3 version is ideal for group trivia sessions and has a nicer presentation, the PSP is perfect for a quick fix or taking your trivia skills on the go. Indeed, the PSP version does also three forms of multiplayer -- online, Ad Hoc (with game sharing support where only one copy of the game is required to play), and pass-and-play local support. Whether starting up my own game or searching for available online games, I haven't had any luck finding anyone to play online yet. I will point out that players can create and search for games that are Long or Short, that use the Main quiz pack or a custom one, and 2-4 players are supported. The pass-and-play mode, which supports up six players, is nice, but not terribly fun. My point being, while several multiplayer modes are included with Quiz World, I think most folks are going to get most of their quizzing in with the single player modes."
