Keysites still have it for about what the original was going for on an average sale. Then you can do an upgrade to the remaster for $15 so it's like 50% less than buying the new remaster.
When I check it in a private tab it seems you can only buy it in a bundle with the Remaster - which of course requires the PSN account. Scum move for sure.
I think you can still get the normal version through a code. There should be some for the old game. Plus releasing a remaster 4 years later is kind of dumb.
Yes, but you can no longer buy just the "complete edition". The only way to get and play zero dawn on PC right now, is to buy the bundle that also comes with a preorder of the upcoming, more expensive, remastered version.
