So, with 1.7 hours on the 'steam' clock it does not look as if i'm qualified to judge this, but i have played a cd version called "I am an Air Traffic Controller 3 - Tokyo Big Wing" way back when which is using the same game play.

Unfortunately this version has the same downside as the older 2008 version: due to licensing issues, you can only play with 'coloured' (= fake) airlines. Since this game originated in 2015, i assumed the licensing issue would have been fixed and the rest of the world would also finally be able to play with real airlines, but unfortunately you will have to pay a lot of money for the base game with fake airlines.

I will ask for a refund as i am not willing to pay full prise for a 2015 game still containing fake airlines, although the game play is very decent.
