Some of the earlier posts talked about a very limited run for a campaign setting, say 3-4 books. FFG did this with Dawnforge and meant to do the same with Midnight before it became clear that the setting was popular enough to warrent more books. The business model is fairly sound, a campaign book, a player's guide, a monster book, and a campaign path to get things started. As a Midnight fan, I've ben happy with most of the additional books, but were they necessary - no, nice, but not necessary. I guess the business side comes down to how many campaign settings do you want/need. TSR got into some financial trouble because they were too bloated with settings that they felt compelled to support. Could or should you try to do an Eberron like start-up every two years? Is that enough to survive as a company?
