With the talk of Dramatic Irony and what the players know versus what their characters know, I thought it would be a fun time to ask this question.
Do you pull your players aside for hidden scenes the other players don't get to know about?
Depending on the group this seems to be more or less popular. In particular I've seen it used a lot where PvP could come up, or where players wanted to surprise the group with ideas. I've also seen it used as a way of the GM playing a meta-game where he deliberately hides something from players, telling them different things away from the table, and seeing where things play out.
Personally, for my current games, I don't do it. I trust my players to be cooperative with each other and myself in telling the story. However, that does mean I lose out on some of the benefits from this technique in exchange.
What about you? Do you use it? If so, why? If not, why not?
