JetSet, an Airport and Airline management strategy game demo has just been made available to play. It is a game where you can manage an Airport, set up your airline, buy planes for your airline and sign contracts with foreign airlines to land at your airport. You can also build airport infrastructure and buy service vehicles to service the planes.
The game is still in development so the demo version only has one playable airport and some features are still missing.
