I feel like a lot of arcade stuff from the late 80's and 90s still look great. All of the CPS1-3 stuff still looks fantastic, I was actually just playing captain commando and still looks solid. And obviously you have third strike, which made my jaw drop the first time I saw it looks just as impressive today. The MVS stuff especially metal slug and mark of the wolves still just looks so good. NAOMI stuff like guilty gear looks just as awesome now as when it came out and likely always will.
And as ugly as a lot of saturn/ps1 era stuff is I do find them kind of charming. Especially model 2 games like virtua cop, daytona, virtua fighter. N64 games on the other hand, boy....not so much. Everything looks like it's smeared in Vaseline it's so blurry, and just in general look like butt. Nintendo made stuff still looks good but everything else god, not so much. Go back and play shadows of the empire and just bask in how down right crumby it looks.
