It is true that not one single podcast exists for AoC, and I would be the first (lets edit this--I MEAN, I would be the ONLY one right now)
What interests me is maybe discussing some of the things going on in game. For example, economy and what is selling, not selling and maybe selling prices (a very harsh point right now, as due to some stupidities, some players continue to crash the market..). Maybe a discussion on some of the main quest lines or dungeons as well. Then finally do some of the news there.
I will have to think about it, and maybe listen to some game specific podcasts to get an idea of formats. But, I will put it on my list and see how it feels and maybe do a test run or two.
So far, I would be looking at a two week window for these. This way, I can compile some of the data from my news and what is happening in game.
Anyways, I better roll...some reason I am not feeling well today, and need to relax.
