Kinda funny. I backed as i think most of us did. And I hardly come to the forums. Second time. Personally. I paid for there experience, knowlege, and ability to craft a tale/world. It dissapoints me a bit how much input could be affected by the community for this game. Everyones, 'I wants' might not be the best for it. I'll have to trust the team can weed it out. That said, at least they are listening which is more then can be said for others. 'shrug' Its an experiment for all involved
As for a private backers forum. I don't think there is much need. Just because a person can afford more doesnt mean others care any less.
