Yes, you'll be able to play Babylon in multiplayer if you buy the Deluxe Edition, but your friend will not be able to do so.I have a question about multiplayer compatibility among the numerous different releases of ciV:
I have the Steam special edition with Babylonian civilization included, and I play against my friend who bought the pressed DVD version. Will I be able to play as Babylon against my friend online, even if in his version of ciV Babylon is not included?
Please note that Babylon is only included in the Deluxe Version and that the Special Edition does not contain Babylon (but some figurines and an art book). I know people use Special, Collector and Deluxe liberally, but they Special and Deluxe are different offers with different properties. See this thread for a detailed description of the different versions.
