ZOMG! I saw a Mario Kart Wii commercial!
It was different from all the ones I've seen, and there were Norwegians speaking, so it's a Norway only commercial, I guess.
I loved it, but to be honest, most of you guys would have hated it. They presented it as a party game, almost like Mario Party, but perhaps even more extreme.
