Someone bumped the total amount up to $667, and then someone else modified his pledge to get the total back down to $666. The pledges seem to be made only so that they can post snarky comments on the KS page.
Tragically, the Kickstarter campaign has been cancelled. He was getting quite a bit of heat for the lack of transparency regarding the funding, as well as his rather casual approach towards copyright violations. He says he is going to "regroup" and will be back in a couple of months. Unlikely.
This is not an endorsement of this game. My gaming group loves playing this; I will sometimes be a good sport and participate. There may possibly be video evidence of this on Youtube, but I'm not sure.
Play The Small World Designer Edition last night. This is the most ludicrous & over-the-top production I have ever seen. From what I understand, Days of Wonder actually lost money on this. The game cost $280.00 and is now available on eBay for somewhere around $1100. Doesn't change the fact that it really isn't a very interesting game, though.
