Honestly, the awkwardness - as long as it doesn't come from the gameplay itself - is one of the things I like most about some of the streams. That one Stream where Hinkle brought in the other two guys from... some other part of the firaxis-team that I can't remember and the three of them were just having a good time was probably one of my favorite ones.
I enjoyed their banter but I wanted hit my head on the desk when the guy kept refusing the deal fearing he would buff the cities of his future enemy. Even by then I knew the treaty would break during a war and his opponent wouldn't have the bonus against him. Thus he gave up on some DC he could have had easily obtained.
This is why I'm leery of watching Let's Play, I'm a terrible player (I can only beat Civ 5 at King with any degree of confidence, and only beat Emperor once) so when I see mistakes I think are blatant rookie mistakes... I die a little on the inside.
The banter and ribbing between them was great though. Hinkle seems like a very nice guy!
