I don't think there is a single exclusive game on PS4 of interest to me.
Same here
Bloodborne?
Persona 5?
Horizon?
You're missing out on some seriously phenomenal games.
I hate Dark Souls 3, no redeeming qualities for me, so why would I want Bloodborne. I hate Persona 2, absolutely boring, sub-par gameplay and stupid drama story, so why would I want Persona 5. I don't like Open World WRPGs (and had more than enough of this kind of game structure from Breath of the Wild), so why would I want Horizon.
This is not to say that these games are trash (though I wouldn't take them if given for free), but they do not match my tastes, which are quite similar to Max's actually.
I'm not buying a console for just a single remake of games I already own. If this game comes to Xbone or Switch I will buy it, if not, then not. Also, these two platforms would offer the greatest upgrade to me, playability with a controller that has the left analog stick in the more primary position, which is worth much more to me than the graphics upgrade. If this was a new game, then I would get a PS4 for it (if it was clear it is exclusive, otherwise I'd wait about a year before buying a console for it if I expect it to be ported eventually).
