Adding another two categories. I'll change the OP shortly on to reflect all the changes, add acknowledgements, and change to version 1.2:
-------------------------------------
RP: The RPG
RP++++++: I am Fred Hicks.
RP+++++: My name appears in the credits of the RPG. Bask in the glory of my geek cred.
RP++++: I am currently running a DVRPG campaign. My players are in for a big surprise when they realize how screwed they are.
RP+++: I am currently a player in an ongoing campaign. We're kicking names and taking ass.
RP++: I own both books, and have experimented with creating characters and cities. I look forward to actually playing the game.
RP+: I own at least one of the RPG books. I've read them in order to gain further insight into the Dresdenverse. I may play around with creating a character or two.
RP: I do not own the RPG , but I have read some of the articles online. I hope to get the books in the future.
RP-: I am not planning to get the RPG. My enjoyment comes from reading the books, and discussing the theories with my friends.
RP--: Even though the books were written with Jim's blessing, I worry that reading them may taint my understanding of the Dresden Files. I will never read them.
RP---: I dislike all Role Playing games. I refuse to waste time contemplating them.
RP----: Role Playing games are the work of the Devil. Anyone who plays them will suffer an eternity of Hell! Paradoxically, I find the Dresden Files to be fun to read, as I actually took the time to figure out my DV geek code.
!RP: The books are an anathema to the Venators. They must be destroyed!
?RP: Is this the rules to the Aracnos game?
MC: Mac's identity.
MC+++++: Mac is God. Nough Said.
MC++++: Mac is a Dragon-level/Archangel/Odin power in his own right. He is granted neutral status by the accords because everyone is afraid of angering him.
