If you haven’t checked out Victoria 2, I three-quarters-heartledly recommend it. The deep convoluted systems are actually really important (and really convoluted) in that one, and there’s a lot of cool emergent stuff from the simulation. It’s also incredibly messy and really shows its age, but it’ll make for some fun hours of play if you use the community patches.

Also, there’s this tool called Cream API that allows running the DLCs for steam games without buying them.




As far as I know there has never been a steam-account-level ban reported from using it, though some people have been banned from individual online games like Rocket League due to anticheat.
