Yoshiaki Koizumi, the director of Super Mario 3D Land, has told the Official Nintendo Magazine that he has way too many ideas for the next Mario game for Wii U. At the moment he has been busy brainstorming ideas for the game and hes reached the point where he has to start narrowing them down.
“As it turns out, I have too many ideas at the moment for Mario games on Wii U. I’m going to have to start narrowing them down and thinking about which ideas might work well together so that the whole system will be an enjoyable experience rather than a hodgepodge of ideas.”
