Trivia

 * Yoshiaki had wanted to always create a boss fight, in where the character had to climb up the boss. He tried to make this happen in The Legend of Zelda: Ocarina of Time but decided in the end to not do that. Later, in Super Mario Galaxy he used a boss named Megaleg that Mario had to climb to defeat.
 * Originally, he wanted to create more levels with Mario having to find Luigi, however he didn't have enough time to do so.
 * Yoshiaki was the writer of Rosalina's Storybook in Galaxy. He wrote the story at night, without anyone seeing him. The next day, he presented the story to Shigeru Miyamoto who was surprised when Yoshiaki told him he wrote the story without anyone around so they wouldn't find out about it. Yoshiaki has said that he would like Rosalina's Storybook to be created into a Children's Book.
