How many of you guys have ventured over to Starcraft 2?

I think I'm just about to finish the single player missions (think maybe 3 or 4 left) and I've thoroughly enjoyed it. I hated SC1; I was a C&C girl from day one so I didn't expect to like this as much as I do.

Even though I've played 16 missions now I still find the structures difficult to differentiate between which makes building a bit of a pain sometimes as there's nothing in the build menu to suggest you already have a stucture. That's one gripe.

I'm going to move onto the co-op missions next before I venture onto multiplayer and get my arse handed to me on a plate no doubt.
