Gow of war 2 was released in 2007 when the Ps3/wii had been realeased for the year and the 360 had been released for two years, so of course this game wasn't going to sell well. I'm pretty sure gow 3 will sell much more than the first one because Gow 3 has already made a name for itself as a great game, It's already recieved critical acclaim from a lot of critics, it's the first game on the ps3, sony going to market this game much more because they have high expectations for it (hopefully).
