Lets say its good racing sim on mobile but more on "arcade" style. Physics are not great, controls are fine, but F1 is just nightmare (in terms of controls).
If you are singleplayer type this game will be fine and u can progress without spending real money, but multyplayer is just straight up p2w. Graphics are nice, car interior and exterior are okay no bugs, no overheating, but overall game is a meh.
Graphics: 8/10
Controls: 6/10
Audio: 9/10
Gamplay: 6/10
Game overall: 7/10
Recommended if you want to spend 0 money, but if you want real racing sim wait for Real racing next or buy GRID.
