Not to piss on the parade, but the stretch goals seem so arbitrary. So, for $2,175,000 they will implement "advanced skill trees", but for a paltry $1,650,000 they won't. So if they only get 2m (you know, walking around money), sorry people, only basic skill trees for you. And they can't possibly implement a "new class and character" until you get to the lofty heights of $3,425,000. So if you don't give them millions of extra dollars the game system will be subpar, compared to what it could be.
Alright, commence the pile-on.
