In app purchases
Good old classic ruined by some of the greediest in app purchases, there are few cars that you have to pay for over $3, 10$ and more than $20 and cars costs diamonds and earning diamonds on this game takes hell a lot of time (same with coins too) , with that much time and price, I can buy myself an xbox one game, instead of buying gems and cars that costs real money, its a great game, but you will be highly disappointed by the freemium system put on this game.
