That’s a lot of Luigis - Mario & Luigi: Dream Team
Nintendo teased that 2013 would be the year of Luigi before, and it’s delivering on that promise with Luigi’s Mansion: Dark Moon next month, a new Mario & Luigi RPG for 3DS (video here), and the New Super Luigi DLC pack for NSMBU. Mario will have his share of titles, too, with Mario and Donkey Kong and Mario Golf: World Tour.
The mishmash of Dream Team GIFs above come from Maxxie, Sootopolis, and Manolizer. In case it’s not clear in that last image, the game takes place in the mind of a sleeping Luigi — does that make this a sorta sequel to Super Mario Bros. 2?
