Consistency is paramount at what level of the game?
The answer depends entirely on the creative goals.
So, did we have meaningful choices? Did we have agency, even if the AI could potentially predict and counter our plans?
Yes, because the creative goal of the game was to simulate characters navigating a dangerous, semi-realistic universe where such an AI could plausibly exist. The tension it created was consistent with that goal. And within that frame, you
did make meaningful decisions, just not always with full understanding or perfect outcomes.
Likewise, look at games like
Call of Cthulhu or
The One Ring. In those systems, your character will, given enough time, go insane or fall to Shadow. There is no escaping that fate.
But that doesn't mean you lack agency. The goal in those games is to see how far your character can go before that point. What impact they can make. Whether they retire with their soul intact, these are meaningful choices tailored to the setting and system's tone.
When you say that it's paramount, it suggests that the absence or hindrance of it automatically results in a lesser game, which is the problem I have with these threads. Even from the OP's initial post, the framing of his definition of player agency is to view games that fall outside their particular definition as being wrong somehow, not to mention you then have others chiming in with asides of "games versus storytelling exercises".
Here’s where I stand:
Yes, I talk a lot about sandbox campaigns, which aim to maximize player agency. That’s my preference. But it’s just that, a preference. I like sandbox play the same way I like the color blue. Blue isn't superior to red. It’s just the one I gravitate toward.
What matters is whether a campaign's degree of agency supports its creative goals, not whether it hits some universal threshold.
So let me ask this:
Have you played a campaign or RPG that offered no meaningful choices or agency? Not just fewer than you liked, but none at all?
I ask not to trap you, but because I suspect that even in such cases, we’d find meaningful choices aligned with the creative goals. That’s the point I’m driving at: the amount of agency should match the goals, not exceed or ignore them.
And when that happens, I’d argue that agency and meaningful choices are present, even constrained, delayed, or subtle.
Hope this clarifies things.
