Halo, Forza, Gears, Battletoads, Ori were some games that they hadon't that they own and the showing for these games were great imo. But they did have lots of nice 3rd party stuff but saying they had nothing of their own doesn't make sense.
Keyword here is "Good". Halo has been getting lower, and lower review scores for years now. Same with Gears. If these two franchises were anything other than FPS games, they would score in the low 70's on aggregate sites, but because the FPS genre appeals to so many people they get higher scores than they deserve. Forza isn't anything new. Just the same old yearly racing game. Might as well get hyped for Madden, Fifa, or MLB.
Meanwhile Sony had Spiderman, The Last of Us 2, Death Stranding, Ghost of Tsushima, and Nioh 2 (PC/PS4 Only).
So five unique and interesting games vs two boring shooters, and a sports title.
