I was one of the Kickstarters for Dwimmermount. I finally have the hardback, map book, and image book in hand. I like them a lot. It was a very long, turbulent process, but the final product is actually quite good. I can easily run a campaign for years with this book.
Parts of the dungeon are fairly standard, which is a good thing. But it
also has a lot of pseudo-science/technomagic bits which work quite well.
The background is cool, and there are different groups of monsters in
the dungeon, and their relationships are mapped. Some work together,
others hate each other. If the players are smart, they could easily gain
allies to help them.
The art if very old school in style. The book is big, and looks like it will take a lot of punishment.
Overall, I'm glad it is finally here. The final product looks to be very
usable, and well thought out. Congrats to everyone involved in finally
getting this setting into print!
