Civilization V: Gods and Kings Expansion (50% Off)
Price: $14.99 (50% Off)
If you've got a strategy bone in you, odds are you've been addicted to Civilization V since it came out. The only problem is that after years of conquering the world, it can get a little boring using the same armies over and over again. Gods and Kings adds a bunch of new leaders, 11 different religions, and a bunch of awesome scenarios including a Victorian Steampunk mission.
