So-so for me
I was hoping for a greater pool of characters like in Brawl (imagine Snake in a Go Kart), but I suppose that would be pushing things a bit too far.
While somewhat intuitive, it isn't enough to keep me entertained amongst the plethora of other Racing Games that are out/soon to come.
It's good, but it's still not enough to shoot itself out of the ballpark, especially with much more competitive games to be released such as Grand Theft Auto IV. (Grand Theft Auto Racing sounds more appealing now)
Pushing that aside, the ability to have different control schemes is quite excellent (I am not really fond of holding a stationary steering wheel while sitting down).
Multiplayer is also remarkable, as Nintendo did it again.
And finally, fixing snaking is a so-so issue for me. It cuts away a tool people use, but at the same time, sorta makes things harder to get that little extra to push forward.
Either way, this game is fun, and would be a good purchase, but it isn't a must.
