I understand your problem, Een, but I insist anyway.
At the club where I play ("la compagnie des jeux", Lodève, France), when we are 9 with a thief, we use to determine the order of play, 9 cards from a common 54-card game. The authors and publishers have designed a very good ninth card, interesting to play, but without providing a place for it! which is an incredible missed. Does this mean that players on BGA have to deprive themselves of the pleasure of playing with the character of the thief, when it would be so simple to fix this mistake as we do in clubs?
I would like to point out that according to me, and others, the most interesting form of this game is at 9 with a thief, followed by the game at 8 without thief, and very far behind, the game at 8 with thief, or the game at 7 without thief, the presence of an NPC spoiling the game.
Greetings with the hope of one day being able to play the thief on BGA with a ninth slot
