I'm wondering whether the player who starts the game with the Queen gets too much advantage, with free VP for several rounds. That player already starts with the most money because of turn order. Awarding the Queen immediately looked unfair to the other players. In the two games I've played so far, this player won, too. I'm sure there was more to it, but it gave an appearance of a big advantage early on.
If another player immediately builds a palace (oops - converts the initial castle into a palace), that could rebalance the early game, but it would also speed it up & leave players unready for the first Masquerade Ball. Not fun.
I'm thinking of leaving the Queen alone in the middle until someone actually earns her favor.
What do you think?
I think this has not shown to be an issue in any of the games I've played.
