Another one I always thought would be fun is a security contractor/business sim.

Basically, it's the converse of a stealth game: there's one (or maybe a handful on harder levels) intruder and it's your job to keep them out. So you can station guards and place cameras and stuff, which all costs money, so you want to keep your spending in check.

There could be detailed orders, like check nooks and crawlspaces, which takes more time but is more thorough, etc. and of course they have weapons with which to stop the intruder, which you can upgrade over the course of the game.

And you'd have other gadgets and stuff that you can unlock as you play too. Maybe even like a Ubisoft-style idle R&D system or something.

I dunno if it would work in practice but I always liked the idea anyway.
