Meta-gaming

[Jhaelen]

I once had a group where one of the players, a really smart guy, was playing a low intelligence character. It was so amusing watching him struggle to bite his tongue when he figured something out that his character would have not have.

It's one of the reasons I never play a character with less than average intelligence. I'd hate if someone told me the brilliant idea I just had was implausible for my character to have thought of.

As a DM, I have a couple of players that have lots of information about the game and everything in it, while my other players are all fairly newbie. I subvert the metagaming expectations of my experienced players by chucking them curveballs frequently. They know that trolls have regen and rend, but this particular batch of trolls also has a template that gives them an AoE attack. Surprise!

As a player, I do my best to avoid being a metagaming jerk, to varying degrees of success. :-/
