THE GOOD:There are toons of stuff to do which means loads of gameplay.
You get to build up your own machine which lets you buy parts win parts change the colour and make your own emblems
There is also a story mode which is 9 chapters long it sounds not much but it takes a while.
There is also a grand prix mode.
And you can even save replays.
And it has realy good graphics.
THE BAD:
It can be hard at times
And can sometimes get boring if you play it to long.
Also takes a while to get the hang of
SUMMARY:
This sums up to be a realy good raceing game
it has 100's of hours more play than mario kart Double Dash I surrgest if you like racing games you buy this.
It can take a while to get the hang of though.
But the attacks you can use on this game makes it fun you can even steal your enemys health!
