I have just got the Deluxe Edition in it contains 2 plastic boxes (like for DVDs). In the main Civilisation box is CivIII. In the other box it says there is a Fan Kit, Conquest, and Play the World but in the box the is only the first 2 and no Play the World. On load them and opening the files I can see no reference to Play the World. Should there be an other disc for this?
