Simulation games, like the ones Maxis used to make (other than SimCity). SimEarth, SimAnt, SimTower, etc. Those were educational and fun.

I also once played a simulation game that realistically simulated running a shipping business where you shipped things by boat, sailing your fleet from port to port, dropping off your cargo and loading new cargo, giving the occasional bribe, etc. while avoiding bankruptcy. I think it was called "Port of Call." It was made a long time ago, and I haven't played anything quite like it since then.
