I hate to leave this review. Played the first 2 non stop & loved them. Spent money on the 2nd a few times to enhance my experience. But with this one I can't justify the amount of money you have to spend. You use to be able to unlock bikes through achievements or other requirements. Now you have to buy them. So far I have spent $20 just to unlock 2 bikes. The gold/silver cost gets so high, You will spend up to $200+ to unlock all bikes. Not worth it. *review may improve with future updates*
