Istanbul is fun little game where you go around old Istanbul as a merchant, collect resources, then use them to buy jewels, the first to 5 wins.  The interesting thing about the game is how you move through town with your “stack” of assistants and leave them in various places to do jobs for you, them pick them up, or call them back to you at the Fountain.  Of course, there are various strategies you can employ to pick up your jewels, depending upon the exact random layout of that particular game.  Another recent addition, only played this a few times but it’s fast and fun and brings plenty of strategy.
