I had always just played Vanilla and yesterday decided to go the full route on Steam and get G&K and BNW and all the add-ons. Now all I have is BNW. Where did Vanilla and G&K go ???? I can find no reference to them other than a G&K DLC add on. Does BNW eradicate the other games? With Civ 4 when you added another level you could still play the previous ones as well? What options do I have to go back and play the previous levels in Civ5 ??? Steam mystifies me in the myriad ways they can make the simplistic into unknown complexity ??? Hopefully I am just overlooking a simple answer. Can anyone explain what is going on???? It would certainly be appreciated !!!!!
