All of generation 8 seems like diminishing returns. I still play games where I go "wow" at the graphics, but I still can "wow" at PS3 graphics as well. Really the average game of generation 8 looks like the best games of generation 7. It's a nuanced difference.
Every generation before had a very dramatic leap going from the previous generation. I remember being amazed at every step going from generations 2 - 7. But at generation 8, we are many years into it, and the games still only look marginally better than generation 7. Resolution doesn't really seem to matter much anymore. Art direction seems far more important.
This generation had a pretty dramatic leap. Your average open world game on ps4 looks miles better then the best PS3 game. Games like the order AND GOW looked like CGI when the trailers were shown, most people didn't believe PS4 would be able to run it. Honestly seem like you just don't wanna be impressed, which is understandable graphics are good enough at this point.
