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
KSP is the best educational game there is in terms of learning to fun gameplay ratio. The physics are simplified, but accurate enough to gain an intuitive understanding of how spacecraft navigate in orbit
