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
Did I ever land on the mun? Yes. Did I ever land on the mun at less than 5,000km/h? No.
But it did finally help me grok "thrust forward to go up, thrust backwards to go down" and some other orbital mechanics.
Landing, with extreme prejudice.
I kept sending out Duna missions then breaking my save with the kraken trying to build a moonbase while it was in transit
I landed on the Mun before the map view was added to that game. You had to set up your whole transfer via dead reckoning, and there was a chart of speeds and altitudes that someone made that you could consult to see your approximate orbit. It was fun!
