I'd like to highlight the latest release. The game is called Airport Mania: First Flight. It has all the basic time management elements but instead of people you are managing goofy looking airplanes! That already makes the game a bit different, but in addition the gameplay really shines in this one. There's a lot of different stuff for you to do and buy as you progress. And once the game gets going it's really hectic. Everyone should definitely try this one. Airport Mania: First Flight is available for both Mac and PC!
