AH is one of my favorite board games ever, although we don't play it real often. Timewise, it competes with rpgs. Anyway, i have bought Kingsport and read over it but not played it yet. It looks great, although like other mention, it seems to ratchet the difficulty up considerably, and we already think AH is pretty damn hard. We play with KiY, CotDP and Dunwich anyway. Whenever we do play, i'm thinking about replacing the Dunwich board with the Kingsport board.
