No flips for you!
Metagaming is an in game issue -- it's where you're playing the game with the knowledge it's a game. I actually discourage doing this, because my games are not predicated on it always being a fair challenge. The idea of mixing up knowledge between the player and the character is an offshoot of this concept, even if it's the most often talked about in relation to D&D. A player coming to the table with a different goal for play isn't a metagame issue -- it's a table issue.OP asked where my line was for metagaming, so I laid it out.
It is definitely like you say, a person problem, not a game problem. But it falls under the category of metagaming to me.
I'm not trying to bust chops here, or be difficult, but rather point out that it does matter that we talk about things where they belong rather than just lumping them under a "badplay" term like how metagaming is often used.
