I learned how to navigate by compass and map from Arma on the account of you kind of need to, to play certain game modes.
I have never learned shit from "educational" games because they all fail at being games. They're tests with some graphics added, that shit is boring and nobody cares, there's no incentive.
Under FALGSOC, every game would teach you at least one skill
EDIT: I learned Sneaking from Gothic because to sneak in that game you have some guy explaining it to you and that came in very handy as a teenager
I learned about arawanas from that amazon trail game.
One of my favorite Arma missions was we all loaded in for a night mission, and I was squad lead, and we realized that the mission designer didn't give us nods. So we did the whole mission with flashlights, flares, glowsticks, and at several points were literally navigating by the North Star (ARMA has an accurate starmap that changes over the course of the year!). Such a cool memory.
Note: Running in to an enemy patrol in a pitch black forest and neither side noticing until you're twenty feet from each other is NOT FUN AND YOU SHOULDN'T DO IT.
