There are unfortunately a couple groups of people who won't buy the game. Those who aren't terribly interested in it, but if someone gives them a copy they might tinker with it, and those who are spoiled jerks who feel the world owes them a favor.
But there are those of us who I love gaming on the PC. And though I may be more mature (old?! never! mature, I choose to say), than some of the folks here, I genuinely feel that if I don't buy the product, who the heck is going to make it?
Why in the heck would Stardock and Gas Powered Games pay employess, purchase software tools to code, pay for office facilities, artists, accounting folks, HR folks, etc. etc. if they weren't going to make a profit?!
Charge a fair price, release a quality product and flourish. And not having to deal with crap like what came with Spore?! Icing on the cake!
