Sometimes it's fun for me, sometimes it's not. It's certainly a relief to have a program to speed it along. I don't play a lot of games in which detailed maps are necessary, though, so it's not a problem I have frequently.
The most I usually need is a floorplan for Maid, and then that's not even strictly necessary. It's not like it's a tactical game. xD I find it helps my players to have a sense of where things are, though. IRL it's a really fun thing to do as a group as well.
@Pureferret I also have some qualms about the light source.
The left-side text has a light source positioned above the central graphic; that's pretty consistent.
The right-side text? The "m" has a light source coming from the central graphic; the "t" and "a" next to it have light coming from above the central graphic; the light source on the last three letters are... I'm honestly not sure, it's not consistent within any given letter.
I didn't say they were correct or consistent for light sources from that point, that's just the best I can figure. :P I would probably have to screenshot it and draw a diagram to make sense of any of this. At a glance, they all appear to have at least two light sources.
