You bought a PS5 to absorb that type of riveting dialog?
Original game is outdated when it comes to quality of assets, character models, facial and other animations, dialogue system, camera shots and other visual (and combat) improvements. It needs to be brought to the standards of Forbidden West without limitations of the PS4/Pro - basically what they're doing now with Burning Shores. I'll gladly buy the game again for the PS5.
I played Zero Dawn on Steam and it was way better than I expected, but I don't remember a single thing outside of the very good gameplay.
I also played Zero Dawn on PC and Forbidden West kills it on technical level. It's like UE4 vs UE5 with its way more realistic and extremely detailed assets (amongst other things), which weren't possible on the PS4/Pro but on top of that there's also gigantic improvement to dialogue system, camera shots, character models, animations and the way everything played out by actors, shot on camera etc.
It should be relatively easy for them to update assets and bring them and overall art direction to the next level, dialogues and cut-scenes needs to be completely re-shot (if they can't use already shot footage and make it work and look like in FW - sort of what ND did for TLOU Remake), cuz there's no half way here.
