Welcome to 2013. The year of Luigi.

I hope you saw it. If not, see it now.
UK Nintendo Direct
Japanese Luigi special.
Personally, I'm excited for the Animal Crossing release date finally being given
June 9th is so far D:
Just a list of Mario games announced.....
"New Super Luigi U" It isn't really a new game, but DLC that let's the main character become Luigi, and has redone all 80 stages to be much more difficult.
Mario and Luigi RPG 4: Dream Team - Takes place inside Luigi's Dreams
A new Mario Golf game.
A new Mario vs. Donkey Kong game.
More Luigi's Mansion: Dark Moon gameplay.

There's plenty of other great games that were announced that I did not list, so you might want to watch it.
