Saying XBOX lacks exclusives is pretty hyperbolic. WW definitely, but for western audiences it's not that bad.There's only 2 games on the list that really matter for MS.
Crackdown (Microsoft)
Gears of War 4 (Microsoft)
Halo 5: Guardians (Microsoft)
Halo Wars 2 (Microsoft)
Quantum Break (Microsoft)
Rise of the Tomb Raider (Square Enix)
Sea of Thieves (Microsoft)
Scalebound (Microsoft)
Is still a solid list.
