Musing on the art of compelled open licensing.
As always, this is a legal flavored existential crisis, not legal advice. If you like following along with my madness, consider subscribing so that you can descend into the void alongside me!
There’s a kind of magic hidden in tabletop roleplaying games when creators build worlds not for ownership, but for others to build upon. That’s the spirit behind Share-Alike licensing. But like any good magic system, it comes with rules, consequences, and a few curses tucked between the lines.
What Is Share-Alike?
At its simplest, a Share-Alike license says:
“If you build something using my open content, your thing must also stay open.”
It’s a kind of creative reciprocity. If you draw from the same communal well of game mechanics, design tools, or templates, you can’t bottle that water and sell it back sealed. You have to leave the well open for others, too.
It’s the core idea behind licenses like Creative Commons ShareAlike and newer TTRPG-specific ones like Paizo’s ORC License and Daggerheart’s CGL (Community Guidelines License).
Advocates of Open Content
Share-Alike advocates share an admirable idealistic perspective and see it as a way to protect the creative commons. After all, it keeps the open world of TTRPGs from being fenced off or bought out by removing gatekeepers (if I build a game mechanic and make it open, no one can come in later and claim exclusive rights over it), allowing others to remix the content (anyone can take what I made and make something new), and building trust in the community (if we all play by the same rules, no one gets left behind or cut out).
All well-meaning intentions.
In this view, Share-Alike isn’t a chain of obligation, it’s an inclusive circle of openness, where you’re included to be inclusive. A circle that keeps growing, widening… including.
Adversaries of the Mindset (Creators, typically)
But not everyone likes that chain, no matter how noble it looks.
Some creators see Share-Alike as a constraint dressed up as collaboration. They argue this world view lacks flexibility (if I use one piece of Share-Alike content, I might be forced to open up everything, even parts I created myself), discourages investment (if I plan to sell or license my game commercially, Share-Alike can complicate those options), and impedes the creator’s creative control (sometimes I want to share some pieces, but keep others private or protected).
These creators want to choose when and how they open their work. They don’t want to be told that sharing is a one-size-fits-all obligation.
The Emerging, Perpetually Complicated, Middle Path
Some try to compromise.
Maybe the mechanics (like stats, rules, dice systems) stay open, but the story (the lore, characters, setting) stays closed. That’s the model behind the ORC License: a split between “Licensed” and “Reserved” content.
It sounds fair. Share the skeleton, keep the soul.
But even this gets messy. Where does a mechanic end and a story begin? What if your stat block tells a story? What if someone builds a closed-world system on top of your open spellcasting rules?
Compromises create complexity. And complexity is where both sides start to pull away.
The Unresolved Paradox
Here’s the core dilemma:
If you force people to share, is it really sharing?
If you let them close off the commons, does anything stay open?
This is what makes Share-Alike so fascinating… and so divisive. It’s a fundamental judgement call on the original creator’s values on sharing.
Do you want your work to inspire others… even if it means giving up control?
Or do you want to protect your vision… even if it means limiting how others can use it?
There’s no perfect answer. Only choices.
So, What Should You Do?
You don’t need a law degree. You just need to know your intentions.
If you want to build something that others can freely expand, remix, and make their own and are looking to control commercialization, Share-Alike may be your path.
If you want more control over how your creations are used, look at more permissive options.
If you want a hybrid approach, be clear about what you’re sharing and what you’re reserving.
Most importantly: read the licenses. (Yes, really.) Or find someone who can help you understand them.
Because licenses are spells. And spells always come with consequences.
