In addition to all the suggestions - check out modding databases like nexusmods or whatever. Many older games that would not fit your definition have graphical mods that will make your GPU work.
Personally I’ve played modded stalker, fallout, elder scrolls. Hell, you can make Minecraft look absolutely amazing, but it’s a pain to set up properly. You’ve mentioned you’re not into horror games, some games also have total conversions available that do a some genre bending too.
Cyberpunk is not that old, but it’s one of the best looking games ever made IMHO.
Witcher 3, also potentially with mods.








Honestly, cleaning up legacy shit code is already a thing, it’s called consulting.
It won’t be a dedicated career field. The AI bubble is at an all time high, and it works now. What people will realize, is that there is more to a piece of software than just the initial code / prototype. AI is amazing at prototyping, it’s fast and it gives the dopamine rush of bringing something online fast. What AI is not good at is actually creating production ready code. Maintainability, security, operations of AI slop code suck. Massively. Adding features by AI to a vibe coded codebase sucks, and all of this is amplified exponentially if the person vibe coding does not know their shit.
The question on vibe coding is not if it will break, but when. And when it breaks, it does not matter if it’s AI or just bad code. It’s a broken app that needs fixing, and that’s just your regular software engineering job.
