OK, so my assumption was correct:
Ori & The Blind Forest
Forza Horizon 3 (if we're only counting one Forza game)
Halo 5: Guardians
Gears of War 4
Dead Rising 3
Halo Wars 2
Halo: Master Chief Collection
I disagree with Quantum Break, KI, Dead Rising 3, Halo Wars 2, and ReCore due to sub 80 metascores. Well, maybe not KI, because it was a good game. Just got shit on by reviewers for having a crummy pricing scheme early on.
Gears 1 Remaster should be in the list though (Even though I really don't like the Gears series.)
Rare Replay is just an old compilation with a bit of resolution, and anti-aliasing spitshine. For every Rare Replay there's a heapton of old PS1/PS2/PS3 titles in the PSN store.
Ori/Cuphead will run on a toaster, so I don't know. I guess they count though. But if a PS4 owner wants to play those games what do you think they are more likely to do? Go out and get an XB1, or boot up whatever ancient 2005 model PC they have kicking around in their basement?
So IMHO , 9 good games that PS4 doesn't have. Two of which are Indies.
