Share something you’ve learned about playing your character.
What an odd question. Ah well, they can’t all be winners.
To be honest, I’m not sure how to answer this one, because I can barely remember the last time I played in an RPG, rather than running one.
So, I’ll go with a lesson I’ve learned about playing NPCs, instead: No detail is established as fact until it comes out during play. So elements of the NPC’s backstory, their motivations, their plans, even their personality — I may have notes on any of these, but I’m free to change them at any time to better suit what’s going on, as long as it doesn’t contradict something already established as fact. They don’t become “real” until they’re played.
The PCs are suspicious of the NPC’s true motives? Listen to what they’re saying — maybe they’ll float a good idea. Take it, and run with it. The players are reacting to an NPC as if he’s annoying? Cool — making him *purposefully* annoying, as a comedic foil.
Nothing is established, until it is. Roll with it.
