This is a fantastic resource for any fantasy rpg. The maps are presented in two formats: one is numbered for GMs to use, and the other is without numbers; to be used as "player maps"
The variation in maps is excellent. There are underground caverns, temples, crypts, village scenes, waterways, hedge mazes, and many more.
Justin Andrew Mason has done a wonderful job in presenting generic fantasy maps to be used in any fantasy tabletop rpg.
