The hell are you on about? First of all Activision made the deal with Sony not Bungie. Next you need to check your history, Bungie was making games way before they got together with Microsoft. Halo was originally intended to be a PC/Mac game, considering the difference in size between the original XBOX and PC community you could make the argument that Bungie would have gotten wider recognition earlier if they hadn't joined Microsoft (though the fact that it was a console FPS is what made it so great). Also I'd argue that the Xbox owes a great deal of it's success to Bungie and Halo. This was a brand new console breaking into a market that was ruled by Nintendo, Sega and Sony who were all well established brands. Microsoft needed a selling point and they identified Halo as a new and exciting idea that could be their very own exclusive powerhouse. Bungie created the game that made Xbox relevant, and Microsoft is still riding on their coattails to this day, you got to keep Halo they don't owe Microsoft shit.
