I don't think its like that. Let's say they use your money to make plastic cups and put popcorn in it and then try to sell you soda in the plastic cup you already paid for. Wouldn't you think, hold on I've already paid for the plastic cup, shouldn't I get the discount?
that analogy is not good.
do you have a problem that the higher tiers getting things like t-shirts and stuff? because they aren't paying to develop those either. I don't think you're game experience is complete if you aren't using a PE mousepad and wearing a PE hat while looking at your cloth PE world map hanging on the wall.
You haven't bought anything from anyone on kickstarter. You donated money. They are nice enough to give you free things based on how much you donated. At best, you bought a cup. They gave you free popcorn. now you want free soda too.
first of all, they don't give me(us) anything for free (plastic cup=game engine, popcorn=gameplay/story etc) I(we) have given them the money based on a promise to make "isometric, party-based computer RPG set in a new fantasy world". Now they are planing to use plastic cup(game engine) to put soda(new gameplay/story) in it. Supporting the project is one thing and I don't have a problem with it, but by "giving" the expansion to the $165 and above, it looks to me like: all below $165 are not worthy enough to get it(please remember that even $20 might be a lot for some people and there's 25000 ppl there). So they should either give the expansion to all backers (not only to $156+), don't give it to anyone at all or at least make it cheaper for backers, because they spend their money to get this project running.
they will use kickstarter money, money you donated to give you "free" things

No. Not at all. I disagree with your assessment entirely. Obsidian should not feel compelled to give away the store because people like you are informed entirely by your own greed.
Actually they should, because store doesn't add anything to the project funding, example http://www.youtube.com/watch?v=nEaY4JYooJk
