Some older consoles might have what you are looking for. The first and second Silent Hill might be a good starting point if you have the hardware to emulate them. If you want something you can get on steam, I would recommend Lost in Vivo. Really good low poly game. You might also want to check out a youtube channel called "ManlyBadassHero" He plays a lot of indie games (Which tend to be heavily 'retro'/low poly themed) to get some more suggestions. Hope this helped!
