On July 3rd Shigeru Miyamoto held a lecture at Tokyo University about working in the video game industry. The full lecture here. Translation by Video Fenky.

Student: Do you think games are something for children to play?
Shigeru Miyamoto: No; I think games are something for all ages. From five to ninety-five, is what I say. Of course, if you pass 95, then you can still play if you want, but... (laughs)
Instructor: With that in mind, the fact that Mario can sell across all ages and all countries is fairly important, I think.
Shigeru Miyamoto: I just want to make games that make high-school girls happy. And high-school boys, too.
Instructor: Pikmin did pretty well, didn't it?
Shigeru Miyamoto: Yeah, it did, but it kind of went down like this. Pikmin 2 will come out this year, though, and I think interest will shoot back up. I've already got the basic idea for Pikmin 3 in my mind.
