In my current game I was offered the Greed Quest. I was charged with acquiring some of Boudicea's Horses which lay just across my northern border. There was a small inlet of water that needed to be crossed. This was all fine. I had plenty of galleys off my coast and I was preparing for a northern strike either against Ragnar or Boudicea neither were being very nice neighbors. So all I needed to do was get some troops to the galleys and shuttle across the bay. I was just going to send a spy into her territory to make sure I wasn't going to send my troops into a slaughter. So 300 turns seemed a very generous time frame. Six darn turns after I got the quest Persia completed the quest after apparently grabbing something in France from Napoleon. Six freaking turns!!
