Very solid mobile strategy game with little to complain about. Like most mobile f2p games, it is pretty easy the first few hours, but then your cash starts to be worth less as the game progresses, so how you spend your money at the start can have an impact on your experience down the road. There still are pretty decent ways of making money over time through watching ads, getting sponsor dollars, etc. Gameplay is fun, and you'll know what your in for after the first few races, so give it a shot!
