For anyone that hasn't tried Crash Bandicoot Nitro Kart 3D, you really got to. This is literally the best racing game for iPod Touch and iPhones available. It is like the equivalent of super mario kart for nintendo DS, so do check it out if you havn't it only costs 5.99 from the App Store, so not too bad.
There are 3 grand racing cups, and two of them are unlocked until you win the previous cup. Winning means either 1st, 2nd, or 3rd place.
Also, while racing you can hit ? boxes for power ups or missiles to get ahead of your opponent.
There is also the quick race option as well as missions which are fun and addicting to play.
Trust me, this is like the best game ever.
Good graphics, and has not crashed on me.
So if you havn't checked this game, Crash Bandicoot Nitro Kart 3D, out, you really got to because one you start playing, there is stopping.
I have tried almost every racing game available literally, and I find this one to be the best, so try it today!
