Great game and concept. But this game is also a pay to win game. In FWC races, my rider is not fast enough to reach the checkpoints on time. i use Marq Marquez and I have upgraded it as much as I can do with coins. Without using diamonds you cannot improve your rider. That takes real money to buy. The purchases should be there but at least the time should be sufficient for a non-paid gamer to finish a race. Please improve this.
