New Super Luigi U makes me smile every time I see it, and this new E3 trailer is no exception. It details some more of the game's 80 courses, with some multiplayer action featuring Luigi, Nabbit, and the tandem of Bucken-Berry and Ala-Gold. If you look closely, you can see Mario's hat at the 0:29 mark.
Weegee might be Tony's homeboy, but he's my dawg as well, and I'm really looking forward to the DLC later this month. As Luigi himself once said, "I wanna be a great plumber like my brother Mario."
Well my friend, you already are.
