I agree with you. Everything I've seen so far is just.... underwhelming.
For such a huge increase in requirements, I'm expecting some major improvements. If I have to squint to see the differences, then the requirements should have stayed where they were. You can't tell me that PlayStation users have to go from a PS4 to a PS5 just to get brighter eyes on their character and a very very minor hair difference. That's asking a lot.
No, I'm not bitter because I don't want to spend the money- I'm running a PC that already exceeds the recommended hardware. I upgraded for Flight Simulator 2020 and Hogwarts Legacy.
The updates in this game just aren't that noticeable. I hope they get better. It'll seem a bit unfair to the player base if they don't.
