Great game.  Along the lines of how much it has changed though, I agree completely with GI.  The things that made this great game unique are either gone or changed; but it's not all bad.  The sight of a giant base that you defend and send tons of units from is awesome, equally awesome is the sight of giant masses of units (and experimentals) absolutely annihilate each other.  Good game, good graphics, good gameplay, but pretty lame story.  So as a huge fan of the SupCom series, I can honestly say this is a great game and look forward to endless hours playing against commanders everywhere.
