Assassin's Creed was the fastest selling new IP in the US when it released.
On the software side, sales were up 62% to $1.3 billion, with Activision's Call of Duty 4 and Nintendo's Super Mario Galaxy besting the rest, followed by Assassin's Creed, which beat Gears of War's previous record of the best selling new IP at launch.
