Check out the feature in this month's Computer Games magazine, if you haven't already. It's penned by Qt3's own Tom Chick, and it's a great read even if you aren't interested in the Tron game (an even better read if you are). It's "chalk" full of interesting sidebars, an interview with Syd Mead, etc.
I'm interested in the game, too. The movie hasn't aged gracefully (though not as poorly as other childhood favorites of mine... cough, cough, Battlestar Galactica), but I still love the visual aesthetic.
