I got Northern Crown for Christmas and was pleasantly surprised, its a fantasy New England Colonies, with Viking Vinland having been successful from AD 1000, England being a fantasy England, etc.
I haven't gotten far into it yet but I'm real dissapointed they split off the gazeteer into a second short hardcover instead of having the two be one big one like they did with Nyambe and the Penumbra Fantasy Bestiary.
I really liked the Book of Fiends.
Dragonlance was good, I enjoyed playing a half-ogre noble in Krynn and I enjoy the pantheon.
I think I got the Troll Lords cities and settlements pdf but was not wowed by it.
Nyambe was fantastic. Fantasy Africa with lots of neat history.
Dangerous Denizens was less exciting than I was hoping for. The art was a bit of a let down compared to what I had enjoyed in their Hackmaster books.
