I've heard about the free (GPL'd) AutoRealms and wondered if anyone with experience can compare it to commercial products like Campaign Cartographer, and if there is any Linux based map-maker I can grab?"
The one I've been most impressed with, and might pick up at Gen Con this year, is Dundjinni
. Anyone else have any software favorites?
