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.
I want all that, minus “challenging” :-) Those times are over for me. There are tooooooo many games I like and I don’t wanna waste it anymore with trying to git-gud for weeks. I got lazy over the years and now seek different stuff.
Sadly the 80s and 90s games i have so fond memories of, I couldn’t bear to play nowadays. It’s like some dream-cars of mine which i would never actually drive because I’m also a nerd and love the tech-gimmicks. And I don’t wanna manually roll down a window. Same with games. Good for you you still love them, that would be awesome :-) Only game I ever actually 100%ed (willingly) was Witcher3. Damn, I’m totally not the gamer i was 3 or 4 decades ago :-)
