I was never that big into online play with Starcraft. Tried it a few times and it was enjoyable but never liked the rushing aspect of it. I'm usually one to build up my base and forces first. Always wished there was a timer of some kind that allowed players to do that before everyone could proceed further into the map. That way everyone had enough time to prepared at least some forces.
I just hope the AI is improved for the offline skirmish maps. Those are still in right? I spent a lot of time doing that. Mostly because I always kept getting interrupted while playing so I had to pause a lot.
I mostly can't wait to see how the story continues. I guess I'm strange in that I love playing RTS such as C&C, Starcraft, Warcraft, Kohan, Warhammer 40K, etc for the story and single player then the multiplayer.
