Random Realm: Trimming the Map

I previously showed how I turned a map generated in Dwarf Fortress into something usable in a tabletop RPG game. At 250,948 square miles, the map that resulted is about 2.6 times the size of the UK, which is too large for a starting campaign. For this portion, I’m going to work on trimming the map down to a more manageable size and making it useful for actual gaming.

Step 4: Trim the Map(s)

Trimming the map is as simple as zooming in on a particular portion and cropping out the rest. Since I used a 24-mile hex scale previously, I can keep things at the same scale here. I’m not resizing things, I’m just cropping. Here’s the cropped map:

I chose this section based on the kind of terrain I thought would make for a fun campaign. I specifically wanted something temperate, with access to mountains, the sea, and not too many deserts. Deserts, to me, suggest a specific kind of campaign that’s different than standard D&D. Not to say that this will necessarily turn into bog-standard D&D, but I’m reasonably confident that I don’t want to run something with a lot of deserts.

 

 

 

Step 5: Convert to a Hex Map

I really like the look of the pretty map that the GIMP plugin created, but I find hex maps more useful on the GM side of the screen. My goal is to ultimately produce two maps: a graphically appealing fantasy map and a useful hex map.

To make a campaign hex map, I’m turning to yet another piece of software: Worldographer. One nice feature of this program is that it lets you drop an existing map onto a background layer to help decide where to place hexes representing the predominate terrain.

For that purpose, the original Dwarf Fortress ASCII map is actually a little more useful, because each of those ASCII symbols roughly translates into a specific type of terrain, which can in turn be represented by a single hex. The DF map, when cropped identically to the prettier map and dropped onto the Trace Underlay layer of Worldographer, looks like this:


 

 

 

 

 

 

 

 

After I add hexes for Terrain, the map looks something like this:


 

 

 

 

 

 

 

 

Next Steps

I’ll need to add more realistic coasts, terrain features like rivers, and make general improvements and tweaks to the campaign hex map.

Mutant Crawl Classics inspired patron for DCC: The Star Child

Image
The Mutant Crawl Classics Kickstarter is winding down to its final days. Using the free rules found here , I ran the Free RPG Day Funnel adventure Museum at the End of Time . Inspired by events that are very likely to occur within that adventure (and happened in my home game with the kids), I designed a new patron usable for DCC. Just a little something to tide you all over while you wait for the MCC game to release next year. Feel free to use, share, or whatever. I welcome feedback and would love to know if anyone actually makes use of this thing. PATRON: THE STAR CHILD Somewhere across the infinite realms of time, space, and possibility, there stands the greatest possible achievement of architectural design: a monolithic solid whose perfect and precise dimensions exist in a ratio utterly pleasing to the cosmos itself. Not only are the monolith’s height, width, and depth in perfect harmony with the divine ratio, but so too are its invisible dimensions, on into

Why is Call of Cthulhu 7th Edition So Expensive?

Image
On the day I backed the most excellent Silent Legions Kickstarter , I had first contemplated buying the brand new 7th Edition of Call of Cthulhu. Thanks to a cool group of gamers I met in Korea, I finally got to take Chaosium's version of the game off my always growing list of "games I own but have never played" last year. We played in a food court, under florescent lights, surrounded by Burger King and Taco Bell patrons, and it was still fun. Better yet, my oldest son played with us and had a good time. I passed on the original Kickstarter but was watching with great anticipation for the new edition to finally see release. For those who don't know, Call of Cthulhu is not a game that changes much from edition to edition. Unlike, say D&D, which is basically a totally different game every ten years or so, a new edition of Call of Cthulhu basically just means cleaned up typos, maybe a format change here, a little rules tweak there, and some new cover art.

Wednesday Dwimmermount: A Few Thoughts on Running the Game (Session 1)

A long time ago, I began to cobble together some GM aids that put all of the pertinent rules of ACKS into a 7 or so page document. Don’t get me wrong, ACKS uses OD&D as its base and is hardly a complicated game. The crunchy bits it introduces to that rules set are all things that I enjoy, such as clear mechanics for hiring henchmen and mercenaries. However, the book’s organization is a wee bit scattered, and I found myself flipping around more than I would have liked. Some of that will go away with experience, of course, but I’m now very motivated to finish said GM aid. As a further thought on organization, Dwimmermount has a few warts. Some of the important general information is set aside in its own chapter (doors, wandering monsters, etc.), which is very good for finding what you need during GM prep, but not so good when you’re trying to find something in the heat of the moment. For example, Zazik’s coughing fit was supposed to call for an encounter throw each round that
