More stealth games that aren't horror and don't allow you to punch or shoot your way out of the situation, should you get caught.
If you have any weapons, make them underpowered to the point of useless in combat (eg. Thief) or you just have gadgets to use that won't help if you get caught (except maybe something that helps you get away like smoke bombs or some shit).
At the same time, though, I don't want that "get caught, immediate game over" thing. You should still be able to run away and hide or whatever. Just make it exciting enough that you don't feel like you need to load up a quicksave.
Similarly (if not directly related to stealth), more espionage/spy games. Not as many as there used to be.
I'd also like more actual detective games. Zero action and preferably ones that let you fuck up a case by accusing the wrong person or making the wrong conclusions and have it impact the narrative. Like, if you get it wrong, you get it wrong and you have to live with that. There are several currently, but I'd love more.
