Not too much different than Beta, same old gameplay but with upgrade graphic.
I disagree for those think that story mode was short, the story definite was more than 10 hours, it might close to 20hours or more, if you wanna complete all achievement, and the challenge mode is quite fun. The cinemac and voice acting is 5 stars. Most cinemac are use game engine.
I do felt that SC2 will be better if their follow command and conquer or war3 element, unit get promoted by the kills and heroes will be nice, there's no merc hire in multi payer game, and some function found in story mode will be nice to had that available in multi player, but isn't fair to non terran player with those function, i bet by last sc2 expasion, we will had all those nice upgrade from the story.
I had play this since Beta release. Graphic and gameplay isn't much different, only limited map and unit stats often change.
Custom map wasn't as good as I hope for, too less maybe more soon, I don't see the metal slug map that youtube show which is better than any custom map I see so far online.
Soundtrack is among the best video game, perhaps best in PC. Definite get the soundtrack if you can. Online mode is what it shine really, but it will take lots of time to master.
Overall is a definite A (9.5) game near perfect just missing few touch, but I expect will be complete with other 2 expasion, don't blame blizzard for release 1/3 game, aleast they tell you in front, most pc game has expasion anyway just look sims. Blizzard won't releae half ass expasion you can count me on, it will bring intereting story and added interest unit or feature online.
