Brian let you all know about SC2VN, the crowdfunded game that communicates some of the real-life experience behind professional StarCraft in South Korea. It's since been made available on Steam for free and is only a ~458mb download, which isn't too bad for what is probably an easier introduction into StarCraft than most streams.
The game focuses on a foreigner SC2 player trying to break into the South Korean scene, your relationships with other players and your attempts to form and maintain a successful pro-gaming team. It's only a few hours long but it's been relatively well received and requires no prior knowledge of StarCraft or eSports. It also looks super nice, so head on over to the Steam page if you're interested.
