RTF is a global modification that replaces all towns in the game.

Such fantasy minorities don't deserve a separate faction. But adding werewolves as neutrals... why not?

By the way, I'm a little confused that bone dragons have become level 6 city units.

It's not a problem to replace "cities" with "towns" :)
To avoid problems (in the future), I can change the title in the topic header, and you can change it in the title.
