>>43347628True. I always feel awfully weird when talking to myself.
I ussually try to bypass the problem by not having NPCs who have reasons for long and meaningful conversations between eachother in the same area during on-screen time. I try to either make them use PCs as an intermediary, hold their discussions offscreen, or make them hold meaningless discussions where neither side is going to change their position.
Of couse, it doesn't always work.
And the funny part is that my players don't mind when NPCs talk to each other and I'm the only one against it.
