It's a pay to win game. They heavily enforce progress by purchasing anything you need to for cars. Getting car parts are impossible unless you purchase gold. Gold is incredibly hard to get unless you pay for it. I played this game for a solid month with little to no progress. At least in CSR Racing you can actually use the money you earned to make your car faster. Ps. Every single car you race feels the same. You can't even tell the difference. Overall a boring game.
