[citation][nom]halls[/nom]7 hours seems pretty short, but they no doubt skipped everything that wasn't directly tied to the main story. Also, this game is very replayable, so I'm not worried about how long the story takes. Hell, I probably beat SC2's campaign in ten hours but have been playing its multiplayer mode since it came out almost two years ago. If you've polished the basic gameplay to a shine, the story is just icing on the cake. I'm level 10 and I can't wait to keep playing later.[/citation]
Haven't played the release yet, but I was in the beta, and IMO the basic gameplay was just ok. Played as a singleplayer game it was even boring. Of course, it was designed as a multiplayer game, though why the NPCs only address one hero is a mystery. Besides, anything is fun with friends.
