In spite of the M&M thread and a couple of others, I was never reallly certain that Dresden Files could be done using the d20 system. Too mathematical, not loose enough for my liking.
Then I bought a copy of Monte Cook's World of Darkness, which takes the familiar lines of Vampire/Werewolf/Mage and puts them together in a 3.5E format. I'm not a fan of 3E but really like the way this book reads so far, in terms of the way the levels are charted out (the classes essentially become "Vampire" or "Werewolf" or whatever) and the magic system is nice because it allows for custom spells (ala SAGA system) and exhaustion rather than a pre-determined number of spells per day. There are special feats for each class/race, as well as general feats for all characters. It just seems to be well written overall.
So why post this on an DFRPG forum?
Well, we've had a few discussion threads about using different systems (like HERO and M&M) to run Dresden campaigns, and the first two settings that immediately popped into my brain when I saw MCWOD were Amber and Harry Dresden. I have no plans to run MCWOD in the actual WOD universe, but now I think that it would be possible to create a d20 Dresden rulebook in a way that could actually be fun to play. I'll bet that feats could be generated for each major group (wizards, vampires, weres, fairy courts, and so on) and the individual groups could correspond to classes.
The spell-casting system in particular just screamed "Dresden" with the rules for exhaustion, etc.
Just thought I would share my enthusiasm. I'm still waiting for the official DFRPG to come out, but in the meantime this may be a nice fit.
