So... how much level i win if i giveaway two valve complete pack? ;)

Quite a lot, probably half way through level 5.

It would seem like a Valve Complete Pack is worth $100 in CV, so 2 is +$200 CV. So that's enough to take you all the way from the bottom of level 4 to level 5 (which requires $150 in CV). It's not enough to get you through all of level 5 though, as that requires $250 CV.

Is god or what?
