How do I start from zero and get to play Market Garden? I have no "base game"...nothing...on my PC. I'm afraid to order, 'cause I don't know which pieces to buy to be able to play the Market Garden form of the game. When I try CM: Normandy I get "You don't need to d/load anything...you already have all the files you need." ???? I actually have nothing, and want to buy whichever pieces I need. Can anyone straighten out the confusion? Thanks.
