Granted I don't have a PS5 yet, but the only answer I can think of is FF7 Rebirth.
Reading that the game takes around 200hrs to Platinum (it'll take me longer I know for a fact), including wading through tons of mini games and a 2nd play through is just too much for me. Not a time investment I'm willing to make.
By association, the release also made me ignore FF7 Remake even with it in my PS+ list. And while I'll keep up with trailers and reviews for whatever the final game is, I know for a fact I ain't playing it.
