The style does vary, they have a "core" group that has members in most of their games with various other cast members spread around. They have a lot of fun, sometimes more rules heavy or light. It really feels to me like a group of friends sitting around playing. Especially in the live streamed ones where there are on air and not edited. Rules discussions and jokes and barbs and a very friendly atmosphere. Their edited sessions ar much tighter but have a bit less banter in general.
