Nintendo President Satoru Iwata and Masahiro Sakurai (the creative force behind both the Kirby and the Super Smash Bros. series) agreed that if all their games mirror games like Wii Sports or Wii Fit, Wii gamers would soon grow bored. Iwata believes games like Wii Sports and Wii Fit were a step in the right direction breaking from the old "more contents and more depth" philosophy and brining more variety.

Iwata
Without a doubt, the rapid speed at which consumers make purchases and then grow tired of them is an area of game development in which the balance has been thoroughly upset. Some time ago we were able to say "if we invest this much effort to make this type of product, gamers should get this much fun play time out of it." Now, however, these odds are changing and there is a feeling that the product won’t hold the gamers attention unless you continually design more game contents and add more depth.

Sakurai
That’s why I think games like Wii Sports and Wii Fit were a step in the right direction. I’m not saying that these games lack depth, but these games proposed an unprecedented line of thinking and broke from the old "more contents and more depth" philosophy.

Iwata
Right, but that absolutely doesn’t mean that we did this because we thought development would be easy. An astounding amount of effort was actually put into the fundamental development process of these titles. We’re investing our efforts in other areas besides graphics and data capacity. However, as I mentioned earlier, if all our games mirror games like Wii Sports or Wii Fit, our gamers would soon grow bored. It’s truly a division of duties.

Sakurai
I agree.
