Well I have not played a multiplayer game mostly because (no one to play with) but I agree all units should be available to everyone and I can see how unbalanced the game would be if one player had special units and another did not. It seems to me that everone should be able to at least purchase the units they do not have. I do not have Grand Battery, Scots Greys, or the Elephant thing and can't get it. This really sucks...A person is just being punished for not preordering, very poor business practices.
