thanks for the kind words.....
To answer your question, we meet over Skype. It would be nice to meet up and record, but that would cut into our huge profits
Japan or India would be fun. But, we just did the Arabs, so talking about another civ that gets Religion free might sound redundant in some places, though they are competely different civs.
We don't meet up to test these civs out, we already do that here and from spending the past few years playing online. We do some planning online, but most of what you hear online is basically us talking to each other for an hour about a civ, and it getting edited down to about 30 minutes or so.
Keep the suggestions coming. We really do consider alll suggestions when planning the show.
