Since I first started playing Dungeons and Dragons and all sorts of other Table Top RPG's way back in 1977 Making maps has been part of the fun and the passion of the game. Creating your own worlds and environment for you and your friends and players to explore and adventure in. Making the maps was fun but in the early day limited to me to only pencil and paper long into the 1980s and early 1990s.
I got my first digital mapping software "Campaign Cartographer" by Pro Fantasy Software back in 2011 this Software Just expanded my worlds exponentially and my desire to create maps for my games. Here is an example of one I created. This map details a Section of the Kingdom of Ageron in my D&D5e Campaign world "Voltera" Campaign Cartographer is basically a very powerful CAD program the more time you spend with it the more you can really come up with some Fantastic maps.
Drawbacks I would say to Campaign Cartographer I would say are its steep learning curve and its price range has not come down in nearly a decade and you could easily pay several hundred dollars if you were to buy all the assets and expansions. This map was created though with just the basic Campaign Cartographer Software and Assets and is Just a snippet of a larger world I created with the program. that is one of the powerful features of Campaign Cartographer is that you can get detailed images of small portions of your map and if your computer is powerful enough make real detailed massive maps for professional print and publication. In addition, it being around for over a decade it more than likely has a lot of how-to tutorials on youtube and the internet.
Another Program I use I just recently stumbled upon Dungeondraft is a great program that is still in Beta Testing but can be purchased for just $20 is great for dungeon masters and gamers on a budget. I found this program very intuitive program, having features geared to those who play online like Roll20 and use a Digital Tabletop arrangement for their games. Since the Covid-19 pandemic I have found myself getting my group together online to keep our campaign moving this Software is excellent for the price and searching the internet I see dozens of creators making assets for it so I think it will go far. The Learning curve is minimal compared to Campaign Cartographer one could easily whip up maps in about 15 minutes. Below is an example of one I made as a 15-minute challenge:
This map again is made with just the basic assets of Dungeondraft and so here are two tools that I use as a dungeon master for my map creation there are many more out there for you and me to discover I just hope you find this small article Inspiration to go out and create your own adventures or maybe try a role-playing game like Dungeons and Dragons or some other. Adventure of the mind and enjoyment await you.
As part of my exploration of maps and Mapmaking, I have taken to Ko-Fi.com to make many of my maps available to those interested in using them for VTT play like on Shard Tabletop, Roll20, Etc.
