Small God of the Dozens
For a new DM it is exactly that. The ability of a DM to manage information increases in direct correlation with their experience. A veteran GM is buying the book for very different reasons. Heck, I don't even remember the last time I ran something "out of the box". A new DM isn't going to be upset about the lack of info though, generally speaking and IMO. I think part of the issue here is that we're talking about newbie DMs and expert level re-purposing of material both in the same breath. A newbie DM isn't going to be field stripping the module and selling it's parts on the black market.Okay. Good. But we may be talking about new time DMs who may be inclined to get this because it is "also a mini setting".
