I'm working on my own submission (thanks for making available not just the game, but all the materials as well).
This will be more of a castle-crawl, because the player will take up the role of a "monster" trying to escape from the Strongold of paladins. Character's background will really be the species - zombie, goblin, mummy...
I think there will be minimal changes from the base rules, as they are very easily adaptable. I will need to make some random tables to better fit the enviroment. I have also already started scouring the internet for public domain pictures, there are many great from old books, one just needs to be able to find them.
There is still much work ahead of me :D
