EDIT: After getting into the game, and playing against other people, I found out that it dosen't lag as much. It's just the main menu that gets me :\
The game play is pretty similar. A few different binds here and there, but it's pretty close. It's like SC BW, but better looking and new units. My base got wiped out by a bunch of the new Terran units. I forgot their name, but they seem pretty strong when concentrating on one thing only. The whole lift off and flying building thing looks so nice. It makes me want to run away every round I have Terran. The maps are pretty nice looking now. The game has a cartoony and cute feel to it because of the models :)
