KSP is an amazing game. More important than anything else, what it gave me is an intuition of orbital mechanics. There's a lot about orbiting craft that's hilariously counter-intuitive to ground-based intuition (favorite example: to approach something, in front of you, you turn opposite to your current trajectory and burn. It shortens your orbit, which decreases your orbital period, which means you'll catch up to your target).
