The game has trading cards, too.

You will get the base game and the following DLCs:

• Civilization V: Cradle of Civilization - Mediterranean
• Civilization V: Cradle of Civilization - Asia
• Civilization V: Cradle of Civilization - Americas
• Civilization V: Cradle of Civilization - Mesopotamia
• Sid Meier’s Civilization® V: Babylon (Nebuchadnezzar II)
• Double Civilization and Scenario Pack: Spain and Inca
• Civilization and Scenario Pack: Polynesia
• Civilization and Scenario Pack: Denmark - The Vikings
• Civilization V: Explorer’s Map Pack

I think given the DLCs included this is a pretty good price for this game.

Enjoy.
