For my Patreon RPG world Arcadia — you can see what I’ve done so far for only a buck a month! — and I pretty much spent the day fiddling with it to in order to learn the basics. This is a small part of it so far; the quality is much better in the original, trust me. I’m using Campaign Cartographer for this one, because they allow commercial use and buying it was tax deductible. I mean, people are paying me to do this stuff. Map-making is a legitimate and recognized part of the roleplaying game supplement experience.
So, yeah, that was what I was doing today. And it’s not as easy as you’d think.
