The only thing I could think they’re saving on is concept art and making the general story beats. A lot of stuff is quite different; it’s not just a coat of paint (like TLOU “remake”).I simply refuse to pay full price for a game remaster/remake or whatever else. They are saving masses of cost vs developing a new game so they shouldn't be charging the same price as a ground up game.
I want to play this but I will pick it up when its much cheaper.
