Ok, this thread isn't actually about matchmaking with players (although it could be!) - I was just looking for a little wisdom about how to promote and direct more interaction between players (and their PCs, it follows) in the game.
I feel like as a DM, especially in the Trad Game/OSR nexus, that I'm conducting several conversations between myself and individual players but very rarely are the players interacting for any length of time aside from table-chat; I'm always involved! PCs don't talk to one another, or really have any formal relationships. How do I find and support the space in my games where player's characters can, say, have a conversation and make the shared world a little richer and a little less computational? What systems might encourage the players to face their co-players and ask questions, rather than all the chairs pointed at me all the time (gulp)?
Any ideas would be useful!
