What's the highest grossing arcade game of all time? What's the longest anyone's spent playing an MMO? You'd know the answers to these and many more questions about the extremes of the video game world if you had a copy of the Guinness World Records 2010: Gamer's Edition. Or if you clicked over to the press release announcing that the book is out today in the US and will be out January 21 in UK.

If you'd like more peeks into the book before you decide whether to buy into this celebration of gaming's most excessive numbers (and most obvious marketing), Guinness posted some preview pages here. And if you want to beat that MMO record, it was 16,799 hours. In Runescape. Have "fun!"
