One of my ongoing projects is to create a combination “setting bible” and tabletop RPG sourcebook for the Human Destiny setting. The idea is to codify the setting for myself, and also to make a little money while cross-marketing it to gamers.

The problem all along has been to find the right vehicle – that is, the right game system – for the RPG side of the project. There’s a continuum of potential options here.

At one end of the spectrum, I could design my own game system from scratch. I’ve done a little work in this direction, producing the fragmentary EIDOLON game system. The advantage there is that I would have creative freedom, and could avoid infringing on anyone else’s intellectual property. The drawback is that yet another original game system, one that doesn’t have any external support, acts as a barrier to potential players.

At the other end of the spectrum, I could license an existing and well-known game system and produce an independently published sourcebook for that. GURPS would be an obvious choice, given my publication history, but I’ve also considered a few other systems. For most of the past year, I’ve leaned toward Cortex Prime as a good choice, on the assumption that Fandom’s eventual licensing schemes would be congenial. In general, the advantage of working with an existing game system is that the finished product would be familiar to many potential players, and would have significant ancillary support.

The drawback of using an existing system – and this is a big one – is that most of the best choices have fairly restrictive licensing schemes. I’m a one-man creative operation with a fairly low tolerance for risk. I’m just not interested in a plan that would require me to hire a development staff and try to crowd-fund with a budget of tens or hundreds of thousands of dollars. That’s why I’ve never seriously considered trying to get a GURPS license, for example. I know people have made a good go of that, but it’s not within my reach.

Recently the folks at Fandom announced their upcoming non-commercial and commercial licenses for Cortex Prime. I can’t speak to how other Cortex fans have reacted to that announcement. From my own perspective only, it looks as if what I would want to do with the system falls between two stools. Non-commercial license means no money at all. Commercial license looks as if it would informally require the development-staff-and-crowdfunding avenue.

Back to the drawing board. Fortunately, there’s another “sweet spot” on that continuum I mentioned earlier. That involves working with a system that’s covered under the Open Game License (OGL).

The OGL is a legal framework which was first established by Wizards of the Coast back in 2000, originally covering the “3.5 edition” of Dungeons & Dragons. Since then, a lot of indie publishers have produced material for a variety of game systems under the OGL.

Working under the OGL, you can use any game mechanics that a publisher has placed under the “Open Content” category, adding your own tweaks to the mechanics and your own new rules systems, and publish the result. There are some legal requirements – you have to include a copy of the OGL in your book, and you can’t expressly claim that your product is associated with the original game. Those aren’t onerous requirements, and they don’t push a project into the staff-and-crowdfunding zone. Plenty of one-man or small-team projects have succeeded under the OGL.

Meanwhile, under the OGL you can also designate your own intellectual property – information about a setting, most often – as “Product Identity” which is still protected by copyright. Which is exactly what I would want to do for game material based on any of my created settings or published fiction.

Right now I’m specifically looking at the fact that the popular SF game Traveller has at least one edition published under the OGL. There’s also a Traveller emulation under its own OGL structure, published as the Cepheus Engine RPG. There’s a whole cottage industry of indie publishers producing material under the Cepheus Engine banner, and some of that material is moving out into a variety of genres. There are Cepheus Engine-based games for hard-SF, swords & sorcery, Old West, and other settings.

The Human Destiny setting isn’t all that Traveller-like in some respects, but I suspect it wouldn’t be all that difficult to produce a Cepheus Engine hack that would do a good job of it. I might even be able to bring in some mechanics from EIDOLON – the two systems aren’t radically different and might hybridize well.

So that’s the current plan for the Human Destiny sourcebook: to rework it as a Cepheus Engine hack and start moving toward independent publication under the OGL. First step in the plan is to start working on the character design rules. I hope to have at least a partial draft of those available as a free release for my patrons by the end of December.
