In Citadels, players take on new roles each round to represent characters they hire in order to help them acquire gold and erect buildings. The real crux of where Citadels shines is the drafting of character roles. Every round the selection of characters that appear in your hand when it comes to your pick will be different and your tactics will influence your choice. But it's more than just cool characters with special powers. The aggressive ones like the Assassin and the Thief throw a new dynamic into the game.
