While the play style of your group is very different from the ones I have experience in -- there is one difference which REALLY stands out to me from watching your sessions.
90-95% of the time, all of the players refer to their characters in the third person.
"So and so says", "he says","she walks over and"...
I have never, ever seen this at our table -- or at any other gaming group or even at a Convention pick-up game. Our groups always refers to their character in the first person. The reference is "I", always "I".
The only "he says/she says" comes from the GM.
Is there a reason your players play in this style and has your group tried playing with "I"?
