Hold that thought because...
Horizon Zero Dawn Remastered forces PSN login for PC users if they decide to upgrade
PlayStation is forcing Horizon Zero Dawn Remastered PC players to log into PSN to play, a restriction not found in the original release.www.videogamer.com
I don't see the problem with PSN
I was happy to link Steam with PSN because then I can track my game progress across PS5 and PC
As for the upgrade offer... Completed Zero Dawn and loved it, but will wait until its less than a fiver. It's essentially just a hi-res texture pack so should be free imo
