I'm a huge fan. Have all the books, almost all of the spinoff products (Mapps, Science Of, Folkore Of, Games, Calendars, Diaries, DVDs, CDs, a few minatures.... and more) and this weekend I'm travelling to Sydney for the
3rd Australian Discworld Convention (my fourth overall - 3 in Australia, 1 in the UK).
I've submitted a question about future computer games to be asked during Terry's interview session (assuming I don't get the chance to talk to him directly myself - after all there'll be 400 people there wanting to chat) so next week I might have some news for you about the /possibility/ of future Discworld Computer games, assuming a deal can be reached between Terry and a developer.
