I am interested in this game but my gaming group is usually 5 players.
On BGG it is listed as a 5 player game but in a couple of reviews it talked about it being a 4 player game.
Can this be played as a 5 players and if so, is it good with that many players?
It is a 4-player game. The description should be changed. You might be able to steal pieces from regular Carc and add a 5th player. But given the added pressure of the city walls closing in on you, a 5th player may make it more chaotic than it needs to be.
