Absolutely amazing. I'm one of those people who only plays through games once they've gone below £10.
19 of the top 50 most played games were new IP's. 4 of the top 50 were sequels to those new IP's.
I think there's 6 sequels: Left 4 Dead 2, Gears of War 2, Rock Band 2, Assassin's Creed II, Mass Effect 2, Gears of War 3.
