ok so my fears were unwarranted about this game. its really awesome and feels just like a sequel should imo, better graphics, continues the story, adds tons of new units and options etc (or changes old ones to make them feel new). If they can do this with diablo 3 then i'm going to play that game for a billion hours
its not as big as the leap from warcraft to warcraft 2, but thats ok with me because the game is a hell of a lot more fun than warcraft 3 was at this point. I'm only about 6 hours into the game but it really makes me feel like I did when I first played starcraft back in high school (ie excited and enthusiastic about playing it right when i get home)
i never played starcraft online and I probably wont play this online either, but I am interested in the Challenges and vs AI, maybe even co-op vs AI? certainly not competetive multiplayer though, I play street fighter and I don't have time to get good at two insanely complex games
