Those who enjoy Thunderstone (and have the expansions) might want to give a listen to Episode #196 of the Dice Tower podcast. Some interesting Thunderstone variants are discussed, including manipulating the dungeon so that the monsters scale smoothly, or using all of your village cards mixed together by type (for example, all of the Weapons mixed in three stacks, all of the Light cards in two stacks). You can follow the link above, then choose Episodes -> Current Episode off of the menu.
