Well im still new to the game but i absolutely love the concept! It works fine, but it IS one of those games with he same repetitive backing track on repeat. And the little cars racing are not even close to represent what you put on the track. I think this game could become huge in the car culture if the decelopers went deeper into the graphics and audio. I love the cards and the balancing, i love i can tune the cars. Im sad i have to merge and spend cars for higher upgrades. and prices 2 high..
