The stories were very different, but the units and the way the game unfolds, in general, is very unique. I really enjoyed how different the Allies and the Soviet stories were. You have two campaigns to play through and they both have a ton of missions for you to get through.
This game is pretty stacked when it comes to single-player content. Two Campaigns Are Great, But Three Would Have Been Sweet! The story unfolds very well and the cut scenes as is the case with the other games in the series are all very well done. Even now, all these years later I think that this is a game that is easy on the eyes. The presentation in the game at the time was very impressive.
