Same ol' Mario, Same ol' Karting
This game got pretty too repetitive, you can say it's an update of the previous GameCube version - not to mention that it's almost the same DS version but with better graphics. You see, Mario is Nintendo's mascot, which means that they know that any game they release with his name in the title is a must buy for any Nintendo fan, even normal non-hardcore fans (especially when they include something with the game like a microphone or a wheel.) I used to be like that, but now, it's different for me, I will only buy Mario games that I know I'll enjoy and keep enjoying even if I wipe the dust of the wii and play that game again 15 years from now just like I enjoy playing Super Mario Bros now.
I'm not saying that this game is bad, I'm just saying that it's a priority to spend 50 bucks on "Wario Land: Shake It" or "No More Heros" or "Prince of Persia" or "LittleBigPlanet" or "Gears of War 2" or ...(You get the point don't you?) rather than spending it on a game that you are just going to add on your shelve next to the other "Mascot" games you have hardly ever used. However, you should know that this game is fun to play with friends and family, but if you want fun for "YOU", then "you" better employ your money elsewhere.
