Campaign Mastery

This article had the working title of “The Penumbra of Personality Traits”, but when it came to actually write it, I decided that readers might find the meaning a little opaque (and yes, that’s a pun, as some will immediately recognize). A penumbra is also a solid metaphor (another pun) for the personality construction technique […]

I have said before that you can never have too many approaches to determining the characterization of an NPC up your sleeve. Today’s article offers a new one, and a systematic way of looking at simpler approaches that can also be useful. Let’s start by setting a baseline for comparison… 0. Going Nowhere: The Null […]

My co-GM and I have almost finished designing the next adventure in the Adventurer’s Club campaign, entitled “Lucifer Rising”. This will be the 33rd adventure in the main continuity (which doesn’t count a half-dozen of fill-in adventures along the way). This adventure is notable for having a slightly different structure to most of them, and […]

Campaign Mastery has already hosted the Blog Carnival once this year, but when Scot (who runs the Carnival for us) asked me to fill an empty slot, how could I say no? Especially when I already had a list of carnival subjects to draw on? So, this is Art-spiration. Pick a painting or drawing and […]

With the conclusion of the Zener Gate campaign, I’ve been thinking about what comes next. In fact, it’s fair to say that it’s been somewhere on my mind for most of 2022, if not always front-and-center. About six months ago, I decided that I would resurrect the Warcry campaign, even though it would need some […]

This is being written more in hope than expectation. Last week (Wednesday night, to be exact), my internet connection became suddenly unreliable. Because it happened late at night, I had the not unreasonable theory that this was because of network upgrades; not only does my ISP not notify customers of such outages in advance, but […]

The Glass Spider – metagame It’s not often that you think of an encounter that would be equally at home in a D&D / Fantasy setting, a Swashbuckling Pirate game, a Sci-Fi environment, a Superhero game-space, or even – if you allow a little genetic engineering to escape the lab – a Cyberpunk game. So […]

Lately, a lot of the spam that CM has been receiving has proposed the use of AI-generated content to make the life of the writer/publisher easier, as though content creation was nothing more than the means to an end. The Flaw In The Argument Mankind has yet to build an artificial system that can pass […]

I hadn’t intended to publish another math-heavy article so soon, but when the muse strikes you have to follow it… To be a top-class GM, you need to have an almost instinctive understanding of probability. Such understanding rarely comes naturally; you have to work at it, exploring different ways of looking at odds and outcomes. […]

This article contains material generated as background reference in Mike’s Doctor Who: A Vortex Of War campaign, but it holds relevance to most campaigns including those of the Fantasy genre. Introduction Space is big – really, really, big. I’m sure most readers will have come across that phrase, or something very like it, on numerous […]

It happens to everyone eventually – you look at your plot and realize that one of your PCs is going to have to interact with an NPC in a one-off scene, an NPC with whom they might never come into contact again. There are many different ways of handling this. Some GMs will use a […]

The story so far… This is the last in a set of mini-posts that I have written and published as quickly as possible (given a number of health-related interruptions), something I’m calling a mini-blitz. My normal publication schedule will resume at the end of the series. Each of the posts so far has examined one […]
