What about something like Kerbal Space Program? Orbital mechanics can get pretty dry, but a game like that can allow us to “play” with concepts and build intuition that we would otherwise have to do problem sets ad nauseum.
Ah yes that is a good one. Maybe it's just rare to make a good game that's also educational. Then again KSP is more fun than educational I think. Or at least, rocket space flight stuff is already such a fun topic to learn about.
