The fourth and final segment of Iwata Asks deals with an often overlooked part of gaming -- sound. The interview also focuses on the design and planning of Wii Fit.

Three of the people Iwata questioned had previously worked on Zelda games, which (as you can imagine) are completely different than Wii Fit. Toru Minegishi talks about the challenges when making music for Wii Fit as opposed to Zelda, which was our favorite part of the interview.

For some interesting anecdotes, and to know what some of the developers' favorite things about Wii Fit are, make sure to hit up the last Iwata Asks, Wii Fit edition.
