So first off, I am soooooooo glad my job during the summer involves me seeing absolutely no one, or I would not be able to listen to these podcasts to pass my time. They're hilariously NSFW. They're also very helpful, because I like the differing opinions and the range of topics covered.
I was listening to the podcast and trying to think of an answer to your question and my thought was "Gaming is a lot like poker and/or blackjack" and then, five minutes later, BAM! Poker.
Way to steal my ideas before I have them.
While I don't have anything to add at the moment (I know, I'm dull
) I do want to comment to say that I really enjoy/agree with the comment of gaming being like improvisational theater.
