Great game but, costly. Super graphics, addictive play, requires good focus. No ads either. One free airport with 4 open gates. New gates cost $2200 to $4800 to open. Five successful aircraft takeoffs earn you $150. So you can see how long it takes to earn enough to open the cheapest gate. You can purchase coins but, thats pretty costly. 1000 cost $1.00. You cant buy the cheapest gate for that. 100,000 coins cost $50.00 but that wont buy all available airports and open all their gates. So, I agree that people should buy some coins to reward the developers for a great game, but there should be a set price for that. I could see $9.99 for the game and each new airport added would cost $1.99 or something like that. Four stars only because of the cost.
