Buzz! Brain Of The UK (Solus)

Identify your friends' trivia weak spots and pass them the PSP system - this specially designed version lets you play wherever you want, with six players able to play together on just one PSP. Each player gets their turn to answer one of the thousands of questions about the UK and then pass the PSP system on, helping select questions for friends and playing on their weaknesses. It makes for hilarious competition - and there's a great single-player mode with 15 trivia challenges to master, awards to win and medals to collect.
