I guess they are quite fun, but I sometimes feel like my maps should tell some kind of story about them. I remember one map I created years ago, I wanted it to be for a game or something and I created the land based on a players journey to find relics. I had the whole thing planned out and even split the regions up into different terrains. I had a frozen region, a dry and rocky region, a heavily forested region, and I even had a dark sort of evil boss region where all the trees were dead and the place was spiky and evil. I guess I just like the idea of maps that tell a story of why places and areas are the way they are. Adds a bit more mystery to the map.
