The beauty of this game is that there is no one goal in the game that should be archived. Each user can set his/her own goal(s). Some goals are pretty clear for me, say to build all possible adventure buildings or to maximize capacity of a terminal / number of planes ... As I see, one of the very popular goal is to have 3 stars on all destinations. What is the point? Award from this is relatively small. I see a sense on early stages of the game when stars allow user to fly to new destinations. But what is the sense in this later (especially when take into account that earning 3 stars for some destinations that require 200+ flights can be boring)? Is this some kind of measure of progress/success in the game?
