Who is Starcraft?

No, but seriously, it's a game, isn't it? Well, I heard about it the first time in the 'NAMKCOR cleaned her fucking room' topic, so... call me 'Terran' (the first name name I found when I googled 'Starcraft'... I looked a bit further, and I think it's the name of the human race? Is it a strategy game? Because the screens make it look like that...)!
