Lol, uhm SC2 in my humble opinion is one of the best games of the decade. I play it almost every day and I'm loving every second of it.
And I love that they give us 3 campaigns that feature everything they want instead of making compromises by giving us 9 or 10 missions per race. Btw afaik the other 2 campaings won't be full priced and well even if they are PC Games are like 20€ less than console games anyway.
