You visit cities to collect goods or fulfill orders. The collected
goods are added to the cities when a player visits a neighboring city.
Fulfilling an order provides you with another better, but more complex
order additional to the fulfilled order which you keep and can fulfill
again, although the number of orders you can own is limited. Each order
itself is worth a certain amount of points at the end of the game. Also
you can exchange these points for special cards which provide additional
goods in certain cities or more victory points if you fulfill certain
conditions at game end.
Depending on the city you want to enter you either receive a resource
called "time" or you have to spend it. By paying a certain time-fee you
are allowed to accompany another player on his trip to a town to
fulfill your orders in this town (but not to collect goods). The game
ends when a player receives the order with the highest value by
fulfilling the order one level below.
