Most of the games on these lists are average and in my opinion, not system sellers. All I learned from looking this up is that console gaming is still far behind PC gaming in terms of 4K graphics and my favorite games like GTA5 and Halo ain't even on any of the fukking lists. What a disappointment. The Nintendo Switch is holding me down at the moment though so I don't mind waiting until they get their shyt together.
