This subject is somewhat odd, admittedly. Technically, I've already built a meta for another game, but it was a miniatures game and I had a far more experienced player build it with me.
Essentially, I'm starting from the ground up. I love A Game of Thrones, the books, games, settings, etc. And I want to share that with other people. I've got around 4-6 players who are either playing the game (and are new to it like me) or are interested in it but have no play experience. And we have a store who is not only willing to host us, but to order anything that they don't carry in stock.
So, that being the case, are there any suggestions on how to really build a league or meta? Where should I start?
