Microsoft had/has multiple exclusives at and near launch. Only one of those three is out.
My wife's favorite X1 game right now is Zoo Tycoon. I've been playing a ton of Dead Rising 3.
I love Forza, but that game and Halo/Gears are not the only exclusives they're bringing.
Microsoft produces or is producing a RPG, Sim Racer, Zoo Sim, 3rd person shooter, open world zombie game, arcade shooter, arcade golf game, a fighting game, a game building suite, an arcade racer, an action hack and slash, a FPS, a platformer, an episodic crime game, a music/rhythm game, an overhead stick shooter, a fitness game, and an open world shooter......and get called out on the variety of what they're pushing for the Xbox One?
