Available via Steam [Link]
I can't let this one slip by without mention. The newest of the Civilization series is available on steam for 29.99, that's 40% off the original price.
If you have a little bit extra I would suggest getting the Digital Deluxe version, it includes:
- Bonus Babylon Civilization with leader "Nebuchadnezzar II"
- Behind the Scenes at Firaxis with Civ V video feature
- Game Soundtrack
Extra content **not available on mac**
If you don't already know, this game is a MUST HAVE. The DLC bundle is not on sale, but with the money you save on the game, you can afford to get it!
