I just finished the first draft of my megadungeon map.
I've rounded out at 375 keyed areas, excluding sub-areas. So likely 450-ish total rooms.
I used Dungeon Crafter with the blue tile set from Dragonsfoot.
It does the job, but it doesn't get style points.
Has anyone bumped into easy-to-use but aesthetically pleasing mapping software? Alternatively, is anyone particularly adept at this sort of thing and want a challenge?
