You said another player can call for it.
No I didn't. I quoted the rule that says the GM calls for Steel test. (Of course other players, or the player themself, are free to suggest to the GM that a Steel test would be appropriate.)
Your example is of a player who put on their "GM hat." You have not outright stated whether that player is a player-player (i.e., someone who only controls their own PC) or the GM (who controls all NPCs).
Actually, I have. At least twice in replies to you:
You mean like here:
My group had a session scheduled for today, but due to various vicissitudes only two of us could make it. The other attendee suggested we start a BW game with the two of us making PCs and "round robinning" the GMing.
And here, in reply to you:
as I've caveated a few times, this is a two-player/two-GM game (each of us frames the adversity for the others' PC), but it relies on the core procedures and principles of BW
Nor have you outright stated that this is a game where any player can control any PC or NPC.
Again, this claim is false. Here is a post made in reply to you:
the most fundamental rules of the system (pp 9-11):
In the game, players take on the roles of characters inspired by history and works of fantasy fiction. These characters are a list of abilities rated with numbers and a list of player-determined priorities. . . .
One of you takes on the role of the game master. The GM is responsible for challenging the players. He also plays the roles of all of those characters not taken on by other players; he guides the pacing of the events of the story; and he arbitrates rules calls and interpretations so that play progresses smoothly.
Everyone else plays a protagonist in the story.
You have said that a character's traits--beliefs and instincts--don't matter re: making a steel test to see if they hesitate before they commit murder, even if the person has traits that put them on the blood-thirsty side and make it so they don't second-guess themselves and therefore wouldn't hesitate. I consider that to be a bad rule.
No. Here is what I actually posted:
I will never admit I am wrong is a Belief. Aedhros was acting on it, in ruthlessly trying to murder the innkeeper. Always repay hurt with hurt is an Instinct, and in this context allows me to assert, with no need for a test, that Aedhros is in the room ready to kill the innkeeper.
They don't affect the Steel test. I could have gone for Mouldbreaker persona, by choosing to have Aedhros fall to his knees and beg for mercy (lamenting his inability to prevent his spouse's death) - but I chose not to. I didn't think that Aedhros was yet at that point.
This post was in reply to you posting that "Aedros (I am not going back to look up spelling) has "hurt for a hurt" and "never admit I'm wrong" as traits. With those traits, saying he might hesitate--that is, second-guess himself and think that he might have been wrong in choosing to attack--was out of character".
I didn't post anything about the effect of traits on Steel tests. As I just posted in reply to
@CellarHeroes, there are traits that can reduce hesitation, and also traits that can change the list of hesitation options. Aedhros has no trait that reduces hesitation when attempting cold-blooded murder.
You said that PC 1 didn't want PC 2 to commit murder
Correct. In fact, Alicia used her magic to persuade Aedhros to spare the innkeeper.
so PC 1's Player called for PC 2's Player to make a roll that could prevent PC 2 from committing murder (thus using out-of-game/metagame methods to enforce in-game wishes).
It was in the capacity of GM, in a round-robin GMed game, that Alicia's player called for the Steel test.
You have claimed that the GM (or player that puts on a GM hat) has no choice as to when to request this roll, but at the same time said that the roll can only be made under certain circumstances, without clarifying how the GM can decide if those circumstances are met.
I've spelled it out in laborious detail: if the general rules for making a test are satisfied (which I have posted dozens of times now, including multiple times in reply to you); and if the circumstances are such as to enliven the possibility of a Steel test (which I have set out in general terms in reply to you and others).
It baffles me that you think this remains unclear.
Also, the circumstances that are required were not present in the given example
Yes they were. As I've already told you, multiple times, committing cold-blooded murder is a trigger for a Steel test (see pp 124-5 of the Revised rulebook; I am not going into the other room to also quote the page numbers from Gold). Initial Steel is also higher for a character who has committed murder in the past; and there are multiple traits that reduce Hesitation when committing murder.
I know that, for whatever reason, you think I'm lying about the rules of the game, and that you know them better than me. But I wish you would stop saying that I've not answered this or that question, or provided this or that information, when - as per the re-posts in this post - it is obvious that I have.
