I got this for the platinum and with the help of wikapedia and google I got it done in 6 days...this game is good for family when i did play by the rules..basically either you know the answeror you dont!...Best part of game is the betting, you can tell what your opponent really think of your smarts based on how they bet against you all the time!
The questions are hard, sometimes bordering on insane. The map questions are terrible. They only give you a green blob of a map, no country borders or names. Also, some questions are factually inaccurate- the first country to give women the right to vote was New Zealand, not Norway as the game states.
