All three game creators are huge fan of Terry Pratchett, and I myself just re-read "Hogfather" about 2 weeks ago.
I promise it was all in three days! 2 of us met up the day before and made a big master list of "themes we'd love to do if they happen to match", but we ended up doing none of them! It was a pretty manic 3 days, that's for sure. I'm unemployed and made this a 3-day full-time job, but 1 other writer was working part-time, and another was working full-time on Monday and taking care of his son over the weekend!
