Basically, not only the player who chooses the profession gets to perform the associated action, but in his turn also all the other players are allowed to perform this action as well. However, as a special bonus the player who has chosen the profession gets some kind of special action: so the Architect may build for less costs, the Colonist receives more Population etc. When all players have performed this action, the phase of the active player ends and the next player becomes the active player, choosing one of the remaining professions in turn. Once all players had chosen a profession, a new turn begins with all professions becoming available once more and the starting player becoming the player left to the last starting player.

These basic playing mechanisms alone stand for a very entertaining gameplay with many possible variations and ample room for strategy, but the rules do not stop here. The buildings which the players may buy for the Capital do not only count for Victory Points once the game is over, but they also play an important role during gameplay. Each building gives its owner some special powers which he may use at his discretion during the game. So a Warehouse allows the storage of goods, a Market allows for better sale-prices etc. Depending on which strategy a player wants to follow, he must chose carefully which buildings he wants to erect, since building space and also the buildings are limited. Choosing to build a special building at the right time might bring a strategic advantage for a player, but nothing can be more unnerving that having a strategy depending on a special building and a competitor building that building and thus making it unavailable for others. In the end, it will be the player with the best timing and planning who will win the game.
