Shameless plug for my game SimAirport: https://store.steampowered.com/app/598330/SimAirport/

I've actually received emails from two academic professors/teachers (collegiate level) who used the game in some form/fashion, as a tool within their courses.

If anyone has an educational use-case for SimAirport, I'd love to hear about it. I'd also be willing to consider providing "site" licenses, or figuring out a license that would work for you, for any solid educational use-cases -- feel free to contact me directly, email is on profile. :)
