I'm not one for madly clicking or remembering build routines; my Starcraft experience is a singleplayer one, so it's nice seeing a long, informative clip taking me through it step-by-step. Reminding me that for all my ignominious defeats throughout the beta's run, there is still a reason for me to get excited about Starcraft.
And that narrator! So homely. It's like he's trying to sell us not video games, but the good old days.
