Mario Kart meet your new rival.
The real great thing about this game is the custimization from building tracks to choosing what your racer and Kart looks like. their is so much to do with this, you can even submit your creations over to friends and the PSN community.
The racing is probaly the weakest part and thats not a bad thing its just the game feels and play like mario kart, the power ups feel the same and driffting and all those steals and tactics roughly work the same as mario kart.
If you have been longing for a great fun racer on your PS3 this is it for you. it will lend you many hours on and off.
