It doesn't match at all. You said that simply using player knowledge to make a decision was metagaming and that's false. It is specifically when you have the character use knowledge that it doesn't have, but the player does. When I have my troll hunter who knows the troll's fire weakness use fire on a troll, I'm using player knowledge to make that decision (your definition), but I'm not metagaming.
Semantics - I know you know what I meant, as we've been through this all before and you clearly remember it since you even know what example I liked to use (the troll and the fire).
And further, your still insisting that experienced players
must act differently than new players because of their out of character knowledge - since you won't let me have my character guess that fire will hurt and scare the unknown creature, because fire hurts and scares most things, and use something besides the same-old stuff I always do because I feel like doing something new.
Your paragraph below is also very wrong.
For that paragraph to be true, you have to prove that a PC can't use fire on trolls the first time he meets one when he grew up near the troll fen and knows all about trolls, or that a PC whose grandfather was a troll hunter and taught him about them couldn't have imparted that knowledge to him before his first troll encounter, or the thousands of other scenarios where a PC could acquire that knowledge in game prior to fighting trolls.
Actually, the things you bring up are
my point - you can't just declare that I'm metagaming because I used knowledge my character doesn't have because there are countless reasons the character actually could have that knowledge, and it's up to me as a player to choose if one or more of them are the case.
Plus, I'm also allowed to have the character guess, or simply take actions they have no idea what the result of will actually be.
The only way to actually define what I'm doing in the scenario as meta-gaming is to police my thoughts by removing my ability to determine my character's background, and by removing my ability to role-play the character as guessing because of what I know (which is using my knowledge that the character doesn't have to determine the character's thoughts/actions, which you claim to want to avoid but force me to do by your removal of the ability to guess).
There is no thought police.
Nonsense. Bringing what I know as a player into the game, rather than only focusing on what the character can know or guess at, is trying to police thoughts.
Only when you force it.
Your suggestion above is more bupkis.
Your bupkis is the only bupkis here.
That's not how people who don't allow metagaming generally run their games, and you aren't required to metagame in order to avoid metagaming. It's absurd of you to suggest that in order to avoid having my PC use knowledge he doesn't have, I have to have him use knowledge that he doesn't have.
You can call it absurd, but I have clearly demonstrated (perhaps not in this thread, but to you on another forum when we previously had the same conversation) that your attempts to separate character and player knowledge beyond a player doing so for themself by deciding what a character does or doesn't know, force player knowledge to cause actions that are different from the ones that the same character played by a completely unknowledgeable player would be allowed to take.
It's a simple test: Any time you think someone might be metagaming, ask yourself "would a completely unknowledgeable player be able to guess, no matter how lucky it seems, at the information needed to attempt the stated action?"
If yes: Not metagaming no matter who takes the action or what they know as a player because the action obviously doesn't
require player knowledge.
If no: Not metagaming no matter who takes the action or what they know as a player because knowing the actually impossible to know is playing in bad faith (a.k.a. cheating), not metagaming.
