Badest game of tbe qorld 3rd class game and the reason is to upgrading because it is take a long ttime to upgrade and if you are racing the and you are on the first the behind racers come with a bosster but there is not a buster there no buster is in the game and when you want wannt to buy a new bike before the first one you can't buy the bike before full updating the the first on . This is a advice that do not play this game and nor install it ok take care and they have to change these things
