Given I am not planning to do that, no. And no, I also do not announce that I expect that my character cannot be forced by the mechanics to react in certain way aside a few mostly magical exceptions, as that is the RAW, thus the expected baseline.
I fully expect the players to create characters that are believable people with goals, desires, values, fears and beliefs and I expect them to roleplay them honestly and react to the things the GM presents. I just do not believe that if they fail to do so this is an issue that can be fixed by the GM railroading them via the rules to play like the GM wants. Rather it is matter that should be discussed OOC, and ultimately if it cannot be resolved, it is the time to find better players.
What on earth are you talking about? You seem to be (deliberately?) failing to understand the difference between your character being affected by something within the world or being affected by the world itself with your character being forced to take an action. As I said earlier
The ways that someone could be directly or indirectly affected by the world or something on it are endless awe alarm shock disgust sorrow rage/anger doubt/certainty respect for deeds/social standing/position organizational backing/etc. the list is absolutely endless. You could pointlessly change the word world to "
fictional situation" if it makes you happy though. None of those examples are "forcing" an action. What they
are doing however is setting the baseline of some discrete "
fictional situation" situation that could be anything from the description of a location/object/creature or a social interaction where any number of endlessly hypothetical ways the world could affect PCs are present.
Having been made aware of that weight being present on a player's PC the expectation is for them to
do the work of accepting that their PC is a fictional entity that is part of the world where the "
fictional situation" is affecting it & roleplay it accordingly. You and
@AlViking have repeatedly stated that the player is exempt from that and it's totally acceptable to simply decide that their PC is able to seize GM power to reshape the world/fictional situation so that their PC is simply not affected in any way. It has even been asserted that a player can do that with no need to justify why they feel it should not affect their PC or have their PC take an action to investigate why something seems amiss in their eyes unless the GM tells them a magical source or there is a save.
Is the quality of your much discussed "mental model" so fragile & lacking that being presented with a "fictional situation" where you are informed your PC is affected in hypothetical ways such as awe alarm shock disgust sorrow rage/anger doubt/certainty respect for deeds/social standing/position organizational backing/etc is something you are incapable of processing unless you personally complete with metaknowledge are also affected with those hypothetical influences as a player -OR- is this really just a roundabout way of cloaking Gary Stu style Main Character Syndrome player attitudes in the trappings of a sturdier shield?
Ok. I failed my fear save. What happens NOW? Explain what happens. Do I get to decide how my character reacts to the fear? Do you roll randomly on a chart? Do you just TELL me what my character does? Please, advise what happens next...
It depends, Not everything in the world that could potentially affect your PC carries with it a mechanical condition like fear & such. As long as we accept your PC exists as part of the game world that is affected by the "fictional situations" the PC takes part in rather than something like an outsider or aberration that can distort the reality of those fictional situations taking place in the game world the answer is very simple. Specifically if the player wants to try their hand at making a case like the drow/spider one in
676 & expect to be held to it for reasons described in
678. -OR- The player could accept that the fictional situation involves their PC being directly or indirectly affected by the world or something on it are endless awe alarm shock disgust sorrow rage/anger doubt/certainty respect for deeds/social standing/position organizational backing/etc & take an action that is colored by that affect they do not feel their PC has an openly justifiable reason to change the affect
