Shigeru Miyamoto has said that Mario games do not need a heavy story, and are not “particularly suited” to having one at all.
While speaking with Wired, Miyamoto was asked about Super Mario Galaxy being the first Mario more of a story to it, and was curious if this was a new direction we can expect for the series.
“I’ve talked to Galaxy director Yoshiaki Koizumi about that a lot, but this time I’d like to go with as little story as possible,” he said. “I’ve always felt that the Mario games themselves aren’t particularly suited to having a very heavy story, whereas the Zelda series is something that lends itself more naturally to that idea.
“We’ve differentiated a little bit between those two, because the Zelda games have had an in-depth story whereas the Mario games have not. Mr. Koizumi is the type of person who, whenever we’re working on a new Mario game, he always wants to bring more story elements into it, as he did with Super Mario Galaxy.
“But in talking with him this time, he agrees and feels that with Galaxy 2, there won’t be a need for as deep of a story.”
Game’s out in 2010.
