For fans of the wildly imaginative Miyazaki animated films, here’s a paper model of Howl’s Moving Castle. It might have some use in a fantasy or steampunk game; otherwise, it just looks like it would be fun to build.
Merlin Larson has a well researched scenario for wargaming the Battle of the Five Armies from The Hobbit.
Doug Larsen has a nice article and scenario for fighting the battle of Helm’s Deep. He has obviously spent a lot of time studying the source material for both the maps and the forces.
