"Microsoft has probably the two biggest shooter franchises at the moment being, Gears of War and Halo. Both have carried Microsoft as their flagship titles and sell well every time Marcus Fenix or Master Chief are called up for duty. You will struggle to find a Sony series that claims to be bigger than those two juggernauts. But after those big hitters, you struggle to find a first party title or game published by Microsoft that is among the "great" gaming franchises out there. Then when you look at some of the games Sony is bringing to the party this year along with some of their other big franchises, you begin to see that some of the games that Sony offers, Microsoft has nothing that can stand up to what they have, and in an age of where Sony seems to be after a "Halo Killer", does Microsoft need some Sony Killers of their own."
