C'mon! It's Mario Kart!
For those of you who don't know Mario Kart, this is probably the best version of Mario Kart for you to pick up. Whether or not you'll enjoy it depends on the kind of gamer you are. If you like Nintendo brand games, chances are you'll enjoy this. It's considered one of the best games for Nintendo DS, and I can assure you that's not misplaced sentiment. This is a solid kart racing game with a bunch of different racing modes (grand prix, vs, balloon battle, shine battle, etc.). Plus, you can race online via Nintendo's Wi-Fi against 4 people worldwide. Hey, when it comes down to it, if you're the kind of person that would buy a Nintendo DS over a PSP, I can almost guarantee you you will enjoy Mario Kart DS.
For those of you who know Mario Kart, you know exactly what this game is. But, it does have one trait the others don't. I can race people across the world on Mario Kart DS from my toilet. 'Nuff said.
