This is a fun game, but you have to spend a bunch of money to experience many of its features. You can only upgrade vehicles so far then it's mandatory to spend money for gold or "fuse credits". I can't enter a lot of the races because the required vehicles cost $10 or more. If upgrades were cheaper I might consider paying. Plus, the tracks and vehicles haven't changed in the 4 years I've been playing. It's a shame too, because the game is actually enjoyable and realistic.

I love this game, but after the first boss, it doesn't give you enough money to upgrade your car. In addition, you don't have very many gas tanks. It takes twelve minutes to get a gas tank, which you use to race, and you only have 8 at a time. The last problem is that in the 3 boss, you need gold to upgrade your car, and the game doesn't provide very much. I had to buy gold to upgrade my car quicker, if not, it takes FOREVER. The graphics are amazing, and the game has lots of challenges.

Graphics are great, and the real cars are awesome. It's fun, until you hit the first boss. After that, the payout for the races becomes far too little very quickly. You'll use an entire gas tank for one upgrade and then have to wait. The races are extremely short, so if you watch ads to increase pay or get more gas, you end up spending just as much time watching ads as you do playing the game. That major design flaw kills the game not long after you start.
