I preordered it before even looking at what it was.
I was expecting to see the SC2 Engine used for SC and Brood War. What I got is the old engine upgraded for moderatly better sound and graphics.
So, it's the old SC, running ok on my computer. I'm disapointed a little. It's still a fun game, but the controls seems a little clunky at times, compared with SC2.
Yeah, when they announced that I was like...no thanks.
They left everything from SC as it was (including bugs) so that competitive players (i.e. South Korea) have as smooth a transition as possible.
