[@Thread Generator SIN] ah, that makes a little more sense. I have tried that tactic before, of stranding people in a place where the only thing to do is introduce each other to themselves. It ended with nobody talking and only keeping to their inner thoughts... lol. What did work though was when they started going on adventures together. Eventually they slowly took interest in each other and formally introduced themselves while staying in character.
Let us get to know each other naturally is what I'm saying. All you have to focus on is the adventure, and your roleplayers will focus on getting to know each other.
