The differance between CMx1 and "CM"x2.

and I'm having great fun with the demo just ordering a couple of Strykers around, telling the passengers to get out and get back in, shaking out into different formations,

Well if just moving strykers from A to B makes you happy, Combat Mission Sans Fun may have something for you. If you dig deeper you will find that this game is a clunky mess and you will be frustrated in your attempts to carry out your tactical plans. The game just dosnt work.
