I am really, really looking forward to this game. However, I'm a FUDGE/FATE newbie (the only FUDGE product I own is "The Collectors"). I understand that FATE is an adaptation of FUDGE. But will I need separate FUDGE rules to play, or is the Dresden Files RPG a complete game in itself? In other words, when I buy Dresden, will I also need to buy the FUDGE basic rulebook from Grey Ghost?
