As an 80s baby I grew up playing Sierra games on PC and one series my brother and I would play a lot was the Police Quest series (along with Space Quest). I found a website where you could play Sierra games (first one I played was Leisure Suit Larry since I wasn't allowed to play it as a kid) and I am considering doing a replay of the Police Quest games and basically a total retro gaming dive until Starfield and Elder Scrolls 6 comes out (my main gaming at the moment is Modded Skyrim, Sims, and Assassin's Creed Valhalla).
Can anyone recommend any good cop games whether old or new?
Since you mentioned Starfield and Elder Scrolls...
For classical still working RPG, Daggerfall Unity
For a good game, but shoddy port if you have ultrawidescreen, Dragon's Dogma.

Obviously not exactly what you really wanted, but these a relatively good. I haven't played the two cop games though, and I am currently playing Dragon's Dogma which is surprisingly good.
I’ve been meaning to get that cop simulator on Steam! Thanks for the game ideas
