Game maps are great.  Even if a large portion of it is just for flavor, places you will not visit in the RP, they're still very helpful for making the world feel established.  If your character is from the Dortani Highlands and I can look on a map and go Oh, so their ancestors passed through the SkrubbaDubba Mountain range to get them here, it just adds to the story.

I like to have map maker characters.  Seems like something that would be handy
