Yeah, this is how I feel about it, too. The game pemerton describes is certainly a roleplaying game, but is also really quite alien to what I think of as a roleplaying game, and although it's interesting it's just not to my taste.
I think what you said earlier about agency is getting to the difference. There are, I think, two definitions of "agency" that people use:
- The ability for their decisions to impact the game world
- The ability for players to make decisions for their character
It seems to me that Torchbearer gives players more of Type 1, but at the cost of less Type 2. I wouldn't say the Type 2 is "taken away" since the players are agreeing to it, or even proposing it, but nevertheless it constrains their choices.
What's interesting is that the Type 1 agency is really being granted to the player, not just to the character. The player gets to make decisions (or give input) that affects the state of the game world, but not directly through the actions of their characters. They get to participate in framing the scene, which in other RPG is exclusively the purview of the GM.
So, a devil's deal: you get some GM-like powers, but in return you agree to constrain your character choices.
Or maybe I'm STILL not understanding this game....
