I would give it a 4.5 if that was a option. Every thing about the game is good and is very addicted but the only problem is the batteries (spent to buy item, and kart) cost alot and you could only get battery if you purchase them with real life money, but there is some people who can't afford it. other than that the games were pretty good and luckily we could buy some item, karts and other things with k-coins but it not really easy to get k-coins.
