NanaOn-Sha head Masaya Matsuura is tossing around the idea of a title for Wii, as he told GamesIndustry.biz's Ellie Gibson at the Nordic Game conference.

Matsuura's game is in the planning stages, and will be "a very casual, one-button game"—something he hopes work will officially begin on "soon, maybe". When it comes to Wii, he appears quite worried about player fatigue: "...it's very hard sometimes. Because can you keep shaking the controller for hours?

"Players can't spend a long time on gameplay, so this can be tough. So I respect Nintendo's activities, but for software designers like us, it's very hard."
