In Dotm now big airlines just quit since they dont wanna pay last two weeks credit. And yes, nothing much to do thats for sure. But when game ended pages comes up its just sad reading when there is only 150 out off 460 airlines left.
So i think there should be a small bonus to the airlines that actually plays to the end.
So if a player has spend 20 credits ore more in one game : 5+15 and plays to the end he or she should get 3 credits back. Just a little carrot to keep players ingame so when game ends you can loock at the end resoults and actually know if you did good ore bad.
