Well, Halo and Gears are miles ahead in quality of MOST, not every single Sony published game, no one every said they were.
The whole point isn't which console has more exclusives it's that Sony has been releasing more exclusives over the past few years and that's why their heavy hitters don't stack up to Microsoft's heavy hitters when it comes to sales.
That and Microsoft is king of marketing. I don't think there is one commercial that made me want to buy a game like the Gears of War commercial did in 2006. No gameplay, just emotion. It made me want to know what the game was all about. Without even seeing a glimmer of gameplay.
Sony can market, their commercials have been great over the years. They simply just don't push their games as much as Microsoft does. You can tell who has all their eggs in one basket. That's Microsoft with Halo, Gears, Call of Duty, and Kinect.
That's the last i'll say on this topic. It seems some people simply don't get it. Or they want to believe that Halo and Gears are just miles ahead in quality of every single Sony published exclusive because they rake in all the sales in 24 hours.
