These are a grab bag of bonus tiles from SkeletonKey Games. All of excelent quality, but varying wildly in applicability to my games. Still, you can't argue with FREE and I picked up the Annual 1 and 2 so as to get a good idea of what other eAdventure sets I might buy.
Having looked at these it seems distressingly likely that the answer is "all of them". Well played, SkeletonKey Games. Well played.
