Interesting. I only like the 2-player game, because our group has seen such pure kingmaking decisions with more players.
Don't get me wrong. I enjoy the 2 player game (its a good game for my non-gamer wife) but I find laying the smack-down on the kind of player who would choose to play this game (a gateway player) a bit of a pyrrhic victory. It just feels nasty...Oh! and the puppy dog looks you get from beginners when you shear their entire flock. Their bottom lip starts to tremble and the tears start welling up while they stammer "bbbut my sheep"
The king-making...It is a problem for this game I guess this ties into the whole sub-optimal move thing I mentioned too. I have been lucky that the people I play with accept defeat graciously and won't cut down one tall poppy to fertilise another. But for me, if it happened regularly, king-making would quickly take this game off the table.
