Buying DLC Civs on Steam
After seeing the new Gods and Kings announcement, I decided to check up on the DLC for Civ V. According to the wiki page, new DLC civilizations Korea, Inca, Polynesia, and Denmark have been added to the base game. I tried to search for them on Steam, but I don't exactly know what to look for, because they didn't come up under 'DLC.' Are they included in bundles or something?
Any help would be much appreciated!
(I already purchased Babylon, and I see that Spain is coming with Gods and Kings, so I can skip that one ... unless it is cheaper to buy now.)
