Coming this month!
"Doctor Luigi is in the house."
That opening line from Iwata during this morning's Nintendo Direct may have shook the Earth, and I'm still recovering. That's right, Dr. Luigi is still coming to the Wii U on December 31st, just in time for the Year of Luigi 2013.
Miis will appear in the middle in some modes, and Iwata notes that the game will be generally easier than Dr. Mario, which is good news for newcomers.
