The CP2077 patch was very expensive to develop, nearly 1.5 years with the entire CDPR team working only on it.
With HZD Sony just needed to hardwire some settings from the PC version to be optimized for PS5, and 'POOF... a 'Remastered' version of a loved game Sony worked so hard on... so not only are you paying $10 for the 'upgrade' (when its actually optimization, which XBox offers for hundreds of titles for free) but those that don't own the physical copy or prefer digital (or are getting a PS5-Pro) must pay the new higher price for to download a 7 year old (I think) game.
By the way, I played HZD on PS4... pretty good combat, but otherwise very mediocre in every other aspect. The open world looks beautiful and the concept art is some of the best I've ever seen, but otherwise its completely unremarkable.
