In a story that should not surprise anyone, the Wii U will not support Gamecube games like the Wii did. So, to those fans of Luigi’s Mansion who want to play the original after playing the sequel when it comes out, they won’t be able to on the Wii U when it is released next year.
While it would have been a nice addition to the Wii U, I can definitely understand not including the Gamecube compatibility in the new system. Gotta put those HD graphics in there somehow (to those who think I am serious when I made that last comment, I obviously know that isn’t the case. They needed the room for the online support).
