4 stars: Amazing game but a lot of the cars cost gold and the upgrade prices for the cars are insane! It makes the game extremely grindy. You also only unlock ackerman angle in the later upgrades. The game also gives little info on the best ways to make money so I'm still confused on which game modes and track configurations to play. Also most track configurations cost gold. I also think the game could be optimized better for lower end devices
4 stars: Seriously the best driving game you can get on your phone/tablet for sure! You actually drive your cars, not click a button repeatedly. Customization is awesome and it seems like they're putting out new content regularly (I.e. cars and graphics etc.) Would have been 5 stars if they didn't make a 2 tiered reward system in the
3 stars: Fun game. The tuning section is very complicated and pretty necessary so that's a bit of a killer. Challenges on tracks are pretty boring. Higher tier cars aren't better then lower tier until their tuning is upgraded to the same level, Which is another deterrent. Different game modes are okay. The multiplayer is fun. Racing someone's ghost. The cars all swing way to easily and end up backwards. But nothing to really keep it interesting.
3 stars: I love the PC version and this is fairly true to it. The physics are probably as close as they can get on a mobile phone. My only issue is the extra tasks to complete a level. The PC version just takes your score, so it's simple and pretty zen....
