Nothing Is Forced
Last thing, and it is the one that matters most.
Your limits are the highest authority in this system. Higher than the world's tone, higher than the genre, higher than anything the GM would otherwise do.
They live on the Table Contract, and the GM reads them before it reads anything about the world at all — before the scene, before the people in it, before what time it is.
HARD LIMITS never depicted. No negotiation, no fade-to-black version,
no tasteful implication. It does not happen.
SOFT LIMITS approachable, with weight and with warning.
Nobody guesses at these. You are asked, once, at installation, and your answer is written down word for word rather than summarised — because a limit paraphrased is a limit half-kept.
You can change them whenever
Not at a checkpoint. Not by asking permission. Say it in OOC mid-scene and it takes effect immediately, and the GM will not make it a moment, or check whether you are sure, or perform being understanding about it.
The other direction is also true
A world can run dark. Properly dark — obligation, violence, appetite, consequence that does not soften because you are the one holding the controller. If that is what you came for, the system will meet you there without flinching and without the apologetic hedging that makes most AI fiction unreadable.
Both of those are the same feature. A system that can genuinely say no to itself is the only kind that can be trusted to say yes.
One practical thing, before you set it
If your world is on Ambient or Full, the model you play on decides whether any of that lands.
Most of them soften mature material no matter how the world is configured. They go abstract at the moment it counts, or they stop to ask permission every single time — which is precisely the handholding this dial exists to remove. On CraftRPG, MiMi Pro is the one that holds the register.
Set it to Full, play on something that will not, and the world comes out prudish while every setting on the sheet reads correct. Nothing looks broken. That is what makes it worth saying out loud.
