According to an interview over at IGN, current Zelda Director Eiji Aonuma was unsure about implementing Wii MotionPlus into the upcoming Legend of Zelda: Skyward Sword - to the point where it was dropped from the game for two months of development. It took a little motivation from Katsuya Eguchi, a developer working on Wii Sports Resort, to convince Aonuma it was a feature worth having.
"Mr. Eguchi came to me and said, 'Look at all these things you can do with Motion Plus, why wouldn't you use this in a Zelda game? It would be strange not to!'" Said Aonuma.
Being that I've never been entirely convinced with the benefits of Wii MotionPlus - Red Steel 2 is just about the only game I've enjoyed using the feature - I'm keen to see if Skyward Sword has the potential to sway my opinion. According to Aonuma, the extra time Skyward Sword has had in development has been used to refine the Wii MotionPlus features.
"This last year we've been testing those ideas, flushing them out, and integrating them into the game, bringing the whole package together," he claimed. "Tying all those elements together has been a big part of what we've done in the last year."
