Awesome game, almost perfect I’ve got no complaint except for some glitches and bugs I find, but it’s very few and not much of a problem. Also, the quality is INSANE and yet it’s a free mobile game, totally should play. But here are some stuff I learned up to now 1) at beginning there’s a tutorial but it really didn’t help, and I learned it the hard way. I’m still not sure if I’m doing it properly, but at least I enjoy it. 2) as said on 1, decent playing skills are required to fully enjoy this game. 3) persistence is also required to get to certain times, and after that it gets better and better. 4) there maybe lag depending on your device. finally I’m just gonna explain what other reviews may say, 1. Some reviews says they hate how higher grade car parts are blocked till they reach certain levels, but I think it is to prevent the difference in performance between players with same playing skill. For example, if a new player that don’t have money matches with players with money, for sure player with money buys better car parts. So there causes a difference in performance of cars and player with money becomes more likely to win, even if the other player has slightly better skills. 2. Other reviews say the cars are too expensive. In my opinion, s15 is one of the best, and it’s one of the cheapest cars in the shop. Each time there’s a new car added, I would buy the new car if I have money and compare it to my s15 (you can put it back to stock anytime, and I do so to compare them)and most of times I end up selling the newly added car to make my s15 even better. I hope that helped, and thx for those that read my looong review all the way.
