I just bought it today at Target. And I must say, this game brings back a lot of memories. When I was younger, my Mario Kart 64 was stolen. Now that I see some classic courses in Mario Kart DS, it’s like a trip down memory lane for me. I played a friend who didn’t have a Mario Kart DS game card, you can play with just one game card, which is awesome, but the person who doesn’t have the game card has to be this blue shy guy. But it still rocks anyway. I haven’t gone wi-fi yet, I haven’t found how yet. If you see any inactivity of me lately on the GameSpot forums, then I’m playing my DS or my PSP.
