Wow I'm actually surprised and honored.
When I got the invitation email and saw the price tag I was wondering if it had all been a marketing scheme.
After all the survey did ask for how many Steam Games I own... and I own over 200 games in steam.... plus a couple dozen outside of steam.
But then again maybe they want dedicated people that CAN pay for the game.
Still it feels good to know that it wasn't some sort of marketing ploy to selectively 'choose' those who would be very inclined to buy/prepurchase a SC game.
Yes I am a sucker for SC.
