Horizon: Zero Dawn for sure. Nothing else comes close.
Followed closely by God of War (not a new IP, but I would still count it for this conversation as it's different enough from all past God of War titles to warrant being mentioned). Bloodbourne also gets a shoutout. I have not played Sekerio: Shadows Die Twice but it seems everyone raves about it, and it will no doubt continue on into the PS5/Xbox Series X generation.
Finally, how does one count Destiny? It launched as both a PS3 and PS4 title simultaneously, but well into the PS4/Xbox One generation (consoles launched in Nov 2013, Destiny launched in Sep 2014). *IF* you can count Destiny as a new IP from the current-gen, then I have to go with that. Easily over 1000 hours into D1/D2 at this point lol
