We had 22 people - so we tied the California Regional. Lots of people from the boards including a surprise appearance from ktom to save us from losing out on the attendance mark.
The top eight break down was:
3 Stark (2 Siege of Winterfell)
2 Baratheon (1 Treaty with the South)
2 Targaryen (1 with two of the North agendas - Free Folk and Last Giants)
1 Lannister
(There might have been more agendas that I overlooked).
People from the boards in the top eight: ktom (Targaryen), finitesquarewell (Targaryen with the North agendas), kpmccoy (Stark Siege agenda), bloodycelt (Baratheon Treaty with the South), and twn2dn (Stark no agenda).
I played Lanni and went 2-2 (lost in the last round to Ryan who was the other top eight player with a Baratheon Shadows deck). I left shortly after the top eight started, the two Stark Siege agenda decks were paired against each other and that one was over in the second plot. The others were just getting going when I left. The environment seemed fairly balanced from a house perspective, at least (not sure about control vs rush vs midrange breakdown). I think there were
7 Stark (4 Siege, 1 Winter)
6 Baratheon (1 Martell Treaty)
3 Lannister (2 Shadows)
3 Martell
2 Targaryen (1 Free Folk + Last Giants)
1 Greyjoy (Winter)
I might more later, though I'm sure others will fill in a lot of the details.
(EDIT: I made this post accurate so that no one will get confused, though you can now see a better breakdown at agotny.net).
Will's Lanni Shadows deck, in particular, was extremely effective at shutting me down with kneeling starting on turn 2. Man that was irritating (but very instructive)....
