I don't remember much of how the first Starcraft progressed, but I'm liking the structure of the single player campaign. The way your ship is like the hub of unit upgrades reminds me of some DS RPGs I've played recently, as well as a little bit of Mass Effect when you get more people on your ship.

I don't know if I can say how far I am, I've done maybe 7 or 8 different missions.

I do know that I'm tempted to take my 12 lb laptop to school tomorrow to play some more in the 3 hours between my classes.
