Dunno, depends on the quality of the port. PC gamers are hesitant now, after multiple Sony shit show launches like TLOU or Ratchet & Clank.
I don't think it'll sell like hot cakes. BUT I know PC gamers will get sexy non chubby Aloy inside of one week. Mod community be praised.
Still haven't finished HZD on PC, but I was enjoying it (in the final third), but yeah that PC port was kind of shit tbh. For the most part, it runs pretty well, but the robot underground areas (Crucibles or something?) seems to run like absolute dogshit for some reason.
With that said I'd be interested in playing the sequel as I enjoyed the gameplay loop, though I suspect I'd probably need a beefier setup.
