I have played Kingmaker a couple of times at gaming conventions, and also own the AH version, which sadly has not been played yet. For some strange reason, the previous owner spilled nail polish on some of the cards.
In one of the convention games, the game owner made a super pimped up version of the game with a 10'x10' wooden board for the map and miniatures for the pieces. One player per house. It was glorious.
This game just begs for a modern re-print. Kickstarter anyone? or let's petition GMT Games!
