Obligitory Smart-Ass Comment Here
We play 2 players game this way, with both A) and B). And a player can exchange money or cards between his 2 families only by spending one embassy token from one family or the other, so only 6 times in the game. And players alternate for the begining placement : one family of player 1, then one family of player 2, then the second family of player 1, then the second family of player 2. And we use Tactical expansion and Teutonic expansion.
But it is still much less fun than a 4-5-6 player game.
What point limit do you play to?
