No, because it's not true.
How so? It certainly seems that a player with the knowledge is penalized compared to a player without the knowledge who happens to stumble upon the answer.
The player who knows that the troll is vulnerable to fire cannot have his character stumble upon that answer lest he be accused of metagaming. So in this case, his knowledge as a player is a detriment.
Can you give me a scenario where the player having such meta-knowledge would benefit his character given your table's take on metagaming? I'm having a hard time imagining such an instance.
Influence does not equal metagaming, though. A player whose character does not know about trolls and chooses to swing a sword is not acting on the player's knowledge. He's acting on the character's knowledge.
Metagaming is allowing out of game knowledge to influence the character's actions, no?
And what about in Aaron's example? The character was near fire...isn't having him go for his sword rather than the fire metagaming? It's the character being influenced by player knowledge. "I hit it with the flaming log from the fire pit...oh wait, no, my character wouldn't know about the fire vulnerability, so I guess I go for my sword instead." That's metagaming.
If a flaming brand is at hand it is perfectly reasonable for a character to use that to attack an enemy. Let's say it was a wolf instead of a troll. No one would bat an eye at a character trying to scare a wolf off with a firebrand. We've all seen it a million times. It is a perfectly reasonable action for a character to take.
But if the player is aware it's a troll, then it's no longer perfectly reasonable...now it's cheating.
Doesn't that seem a bit harsh to you?
Sure, but it doesn't have to be pure. It just has to not be metagaming.
Ha I meant "pure" as in "free of metagaming", so I'm not sure what you mean...
It's similar enough. The option to use player knowledge that the PC doesn't have is as absent as the wizard lacking the ability to cast divine magic. The option to be inspired by in game facts is as present for the experienced player as it is for the newbie.
No, it's very different. Mostly for reasons I've already stated in my last post, and also above in this one.
That's because you have a different definition of metagaming.
I don't really think it's our definitions that differ so much as our tolerance of it.
At some point my PC will realize none of his weapons will work, and if he has access to fire he will try it.
At what point? When is it okay to decide "all right...my character has come to the conclusion that perhaps fire will harm the creature more effectively"? Is it only once you've exhausted all other options? Is it after X number of rounds? Does the DM decide "okay enough's enough" on a whim?
All of these are still metagaming. You cannot unknow what you know. A player that knows the trick and playing a character who doesn't know the trick is fundamentally different than a player who doesn't know the trick playing a character who also doesn't know the trick. Would you agree with that?
