I agree with Don. I've backed over 200 projects on KS, and it's VERY easy to get excited about a project initially, but have second thought about price, the ability of the creator to deliver (not in this case, of course), a gut feeling that something with the item isn't quite right, or the day of reckoning when you check your list of what you're backing, add everything up, and then meet reality face to face when you consider the chunk of change that you're dropping! I've dropped a few projects in the past, but only because things start looking fishy with product capability claims, the lack of ability for a creator to deliver a product, or too many small issues popping up that aren't addressed adequately by the creator. I've seen a lot of folks drop pledges simply because they want to be a part of the initial rush of group excitement, but then decide that it's not for them. Sucks for both creators and other backers.
I'm excited to see this project remain fully backed and I'm eagerly anticipating the cards! Another great and fun project!
