Well, for over a year now at my desk, a prototype program of Luigi and Mario has been running on my monitor. We've been thinking about the game, and it may be something that could work on a completely new game system.

I never really participated in specific sports or anything, but once I hit 40, I started to get a little bit more active and began swimming more.

Our job as the game creators or developers - the programmers, artists, and whatnot - is that we have to kind of put ourselves in the user's shoes. We try to see what they're seeing, and then make it, and support what we think they might think.

A great idea solves multiple problems at the same time.

All the time, players are forced to do their utmost. If they are challenged to the limit, is it really fun for them?

Originally, I wanted a machine that would cost $100. My idea was to spend nothing on the console technology so all the money could be spent on improving the interface and software. If we hadn't used NAND flash memory and other pricey parts, we might have succeeded.

I think what a lot of people see as unique is using different technology or different techniques [to make games], but I feel like, as long as you have a core that's unlike others, that's what 'unique' is.
