I went ahead and got the full version, and I really enjoy. I also found that my fiancee loves playing it too. It's kinda funny to see her get frustrated because an airplane is getting mad at her.
Then I went and got another similar game, I Am an Air Traffic Controller 3, which is pretty realistic. I love it, but my fiancee, not so much.
