Board Game Quest has posted a review of Istanbul (make your They Might Be Giants joke here) over on their website.
From the post:
I’m going to spoil the suspense right now by saying that I really love this game, and its award was well-deserved. If you haven’t played Istanbul yet, get yourself a copy and be prepared to be whisked away to a frantic bazaar area where merchants are scrambling to acquire more gems than their competitors, to position themselves as the most successful trader at the bazaar.
Istanbul is a pick-up-and-deliver type game, designed by Rüdiger Dorn. It plays 2 to 5 players and takes about 40-60 minutes to play. Istanbul plays best with 3 players.
