Really interesting free-flowing interview, quite different from many of the ones I typically see, especially from Miyamoto. Even in '89 they were grappling with some of the same issues developers are dealing with today, including the trap of pursuing shallow "realism" and the perception that there were no fresh ideas out there.

Also, it features this prescient quote from Miyamoto:

Miyamoto: I think there are still plenty of possibilities in game design. For instance, imagine a game where you input something, and when you check back a month later, it's transformed into something totally unexpected. We don't have anything like that, do we?

Or, take how people living in apartments today can't keep pets. If someone who was obsessed with the joy of having a pet made a game that captured that feeling, I think it would become a huge craze. And since it's a simulation, you could even include the "unfortunate" parts, like the pet eventually passing away, as part of the experience.
