Thanks for the kind words, folks. I've got to tell you, the lion's share of credit goes to my players for coming up with all the cool things during brainstorming.
As for using this without modification, don't. Go beyond modifying it: build your own. It's not that I'm not flattered at the interest, but the co-operative building of the setting is so much fun, and gets you such amazing investment from your players, that I really think you're going to be missing out on something special if you pass it up.
So, sure, steal the ideas you like, but make it fit your game group. Get the players involved, and you'll be amazed at the ideas that come together. The structure for city building really gives you a fun, interesting setting, ripe with adventure hooks and emotional ties for the characters.
At least, that's my suggestion.
