4 stars: Having fun with it, used to race when I was was younger. Hard (or expensive) to up grade but fairly realistic. Wish I could control my own acceleration and breaking though. Still figuring it out, how to navigate through different areas,etc. Being 70 yrs. old could have something to do with it, lol. I'm getting there.
5 stars: Very interactive and full options. Once you learn to manuever through the options you can learn to improve skill. Very fun to build and acquire vehicles. The challenges keep you engaged. And the rewards keep you coming back to customize your vehicles. The vehicle selection keeps you from becoming too familiar with game play in order to improve your overall performance.
3 stars: Tracks are realistic as are the cars but the races themselves are very unrealistic as in pass 22 cars in 1 lap and win the race, real racing that would almost never happen. When entering competitions to win race cars it is a way to get you hooked then in order to complete the competition you will have to pay something or loose the event and car.
5 stars: One of the best racing games on the play store. The grind can be a little tedious at first with some of the wait times but as you unlock more cars it doesn't affect you nearly as much. From what I can tell nothing is 100% locked behind a paywall either. Also I fully recommend going from the default control settings to the one with manual acceleration and breaking with tilt steering.
4 stars: Love the game....
