Well multiplayer support is coming since the newest stand alone expansion called Rebellion is a Steamworks game now.

Graphics get an update in Rebellion as well.

Campaign wouldn't do you much good in the PvP arena since campaign's run on specific scenarios when as multiplayer it runs on various strategies sure there are standard things that everybody does for their respective factions but that's about it. Also a campaign in a 4x RTS game is a bit awkward. The point is to build up your empire from this single planet not do various missions. It seems too slow paced in my opinion for the fast pace of quick time events and such.

Tutorials could use expansion and such. The tutorials are really lacking. It tells you nothing of proper unit counters which this entire game runs on.

Conquest: Frontier Wars (think Starcraft w/ this gameplay) had a campaign and made it work. Large scale objectives without short deadlines. In fact, they were one of the first to have a game with this type of scope. Not quite as structured, but very similar. SupCom helped to bring about the smooth transition from strategic to tactical and Sins just put the two together. It's an obvious evolution that someone had to cash in on.

Games without campaigns are crap.  I picked up SOASE, played for a week before being bored to hell, got sick fast of MP issues and players, and was just about to dump the game until I found Mods & Modding.  It's the only thing that saves this game because it doesn't live up to the description StarClad gave.  Rebellion -hopefully better by miles and not just more neat crap.  Blair's finally pitched in about the game and it seems worth buying.

My mistake was thinking SOASE would have real depth.
