I was also hugely disappointed by this game. You know it's a bad port when the text is so small you need a magnifying glass to read any of it -- and there's a LOT of it, between the menus and on-screen messages you constantly receive at the beginning of the game. The menu cycling is also difficult to maneuver through, adding to the frustration.
As much of a TRON fan as I am, I didn't really care for it, though I'd like to try the PC version sometime.
