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?
No problem. 👍
If you're looking for something more light-hearted, check out the Sam and Max series.
It's detective work with puzzles.
Here's a video of the first game, check out the first 5 minutes to see if it's something you'd be interested in.
