A planned part of my creative strategy is not just to write stories and novels, but also to integrate the world-building elements of those projects into tabletop game material that I can also sell. Basically offering myself a license to my own IP, and self-publishing game material via DriveThruRPG or a similar outlet.

That suggests framing that creative material within a genre-agnostic game system. After all, my two primary creative projects involve heroic alternate-world fantasy (The Curse of Steel and its sequels) and relatively hard-SF space opera (the Human Destiny setting). Any game system that could cover both is not going to be strongly bound to any existing setting or genre.

So the question arises: do I build such a system of my own, or do I find an existing one that works for me and has friendly licensing terms?

I have been gathering design notes for a personally owned game system, under the working title of EIDOLON. There would certainly be no licensing issues there. On the other hand, time spent designing a completely new tabletop game is time I’m not writing. Also, a completely new game system would start with zero market presence. Why should anyone buy such a product, when they would almost certainly have to convert the material to their favorite system before using it?

GURPS is certainly a possibility. I’ve been a GURPS player (and writer, and editor) for many years. Unfortunately, it’s been a long time since I did any work for Steve Jackson Games, so I’m no longer in close contact. In any case, the GURPS licensing terms are pretty strict. Far from impossible to work with – I’m certainly aware of other creators who have published their own GURPS material for sale – but maybe more trouble than it’s worth for what I’m planning to do.

I’ve considered using FATE Core, which certainly fits the criteria (setting- and genre-agnostic, and very congenial licensing terms). Unfortunately, that system is a little too rules-light for my taste. I’ve never quite been able to wrap my brain around how it works in play, so writing material for it feels like a bit more of a challenge than I’m after. I may just need a little more crunch in my game rules.

I’ve glanced at a few other systems over the past couple of years – notably the Genesys system from Fantasy Flight Games – but nothing has quite hit the sweet spot I’m looking for.

Now I see that there’s a new edition of the Cortex system out – the Cortex Prime core rules. These were Kickstarted back in 2017 and have just been released to the public.

Cortex Prime doesn’t look like a playable game right out of the box, so much as it is a toolkit for constructing playable games. Well, that’s true for systems like GURPS or FATE as well, so that’s certainly not a drawback. Reading through the core book, I’m getting a good feeling for the system’s crunchiness and flexibility. Previous editions of Cortex have carried fairly generous licensing terms, and the current publisher seems interested in following suit.

Hmm. I may have to contact them and see if this would be a good fit for what I want to do. If it does work out, then EIDOLON may go on the back burner. Or off the stove entirely.
