Sad news. His was an original mind. As others have said, he seemed pretty restless, always wanting to try something new. The quote about curry is even funnier knowing that his company WARP, inc. actually released their own curry once. I remember a picture of the UK Saturn Mag's Japanese correspondent tucking into a plate in the name of good journalism.
It's interesting the learn about his history of developing games for the blind; he used elements of that in Enemy Zero. The aliens were invisible and could only be located by radar beeps, which changed in pitch based on their direction, and changed in frequency based on their distance. It remains one of the scariest games I've played.
This quote from the interview at 1up offers a good philosophy and seems particularly poignant now:
I have no interest in my own past -- like, what I did in the past, what sold, how much, and so on. And the same goes for other people; I have no interest in what other people did in the past. So, like, instead of working on something I did in the past, I would rather be working on something new. I want to move forward. You have a short life; you're going to die someday. So I don't want to waste my time looking back on something I did in the past. But if I get into a really critical situation where I'm forced to do that in order to make a living, I might do that. But until a critical situation comes up, I'm not interested in looking back. Life is short! There's no time to look back!
