Only in some servers where people would like to experience additional emotion. It ll be like a tournament server where people go to put all of your habilities and expect to anchieve prizes for sucess and right way of flight. You ll participate if you want.
If you fly well you ll save your money and earn some, if you fly bad you ll lost it. It could limit 20 dollars (or 10 lifes) per credit card in a month to preserve people to get vicious and spend much money.
If you pass this limit then you ll go to fly in free dogfighting server to maximize your flying until next month. Hehe...
