But then the steam buyers are getting a nearly finished game and little risk. The average KS plege was actually $48 so a lot of backers pledged for more, took greater risk(as all KS projects are) and made what's on steam now possible in the first place. If someone is upset about the Steam version not including all that then they're wrong, dead wrong, since the game wouldn't be even close to being as good as it is now without the KS backers.
