Game is fun.. for the first 2-4 hours, then it just gets too exhausting! They force you to upgrade your vehicle after every 2-4 races. At first they show it as warning, and then completely disable the feature unless I upgrade my vehicle. I don't need to be told that I can't handle the next race without getting a better vehicle. And you know what, I bet I can. Desperation to force people to pay for the upgrades and better features reeks in this game. Make it a paid app. Avoid nonsense please.
