I feel you. I pretty much exclusively play 80s and 90s games.

You want some fun that is modern, somehow ancient, and beautiful? Oh, and challenging, but if you persist it is very rewarding?

Cuphead. I fucking love that game. I play it and replay it and play it some more. I have waaaaaay too many hours in that game on Steam and on Switch. I think it’s the only game I ever got all achievements on.
