Hey just a quick note. I bought Mario Kart Ds for my daughter bithday on Sept 4. Last weekend my son asked to set up a wireless conection(well the WEP Key) on the DS, then he told me that the game can be play against others ala Xbox Live, he played the whole weekend. Now my daughter and son keeps fighting over the DS(which is the original model), he doesn't have one because he's a young man now(well he told me that, he's 14 ). He actually didn't play Halo 2, or with the X360, is kind of addictive I should say.
