The PSP version sees a whole raft of portable Buzz! firsts that makes it an irresistible offer to people who like to take their trivia on the go. As well as the 4,500 questions that you get with the game, Buzz! Quiz World gives you access to the MyBuzz! quiz online portal so you can personalise your quiz with questions that you and other players have written - previously a PS3-only feature - and you'll also be able to download extra quiz packs from PlayStation Store to tailor your game to your favourite topics. And - just as exciting - this new title lets PSP Buzz! fans play online with other players from around the world, as well as with up to four friends in the same room. There's a new, improved Pass Around Mode too where six players can play with just one PSP, passing it between them for shared trivia action - and an enhanced single-player mode that lets you unlock new characters and earn trophies to prove that you're a bona fide quiz master.
