I found the game to be extremely entertaining and am enjoying it a great deal. I feel that the interface has been... Well, vastly doesn't even begin to describe the ease with which Starcraft 2 flows in every respect over Starcraft 1. The new battlenet is -amazing-. I've been playing games against random people all day and the manner in which is sets these, dare I say, discreet rendezvous is titillating.
My gameplay virtually smolders with unspoken lust.
The story was entertaining and, I feel, very well executed given the platform. Given that it's an RTS I'm more impressed that they've delivered enough of a story to set the virgins of the world ablaze with indignation over the likelihood of Mar Sara being a world of smoldering glass or the verdant paradise which is presented.
Furthermore Kerrigan's hair was a lighter shade of red in SC 1 than in SC 2. I'm writing Blizzard to demand they explain this oversight. So don't get too invested, I expect the game to be recalled shortly.
One thing which I find rather annoying is the lack of support for extra-regional play. Most of the people I play with are outside of the states (as most of the disco people I know of who play SC within the USA annoy me something fierce).
