Requires purchasing upgrades in order to advance or to unlock planes. There is no option to earn advancements by playing or mastering the "game". I wouldnt call it a "simulator", only pitch and roll characteristics, no yaw (rudder) No gear controls, no flap controls, no taxi brake control... graphics are mediocre. You earn "coins" but theres nothing to spend them on. Too simple to fly, not challenging and no incentive to keep playing. As I said, disappointing. Feels like a 90s-era game, not 2015.
