Seriously poor form to create an item like this and essentially turn it into a KS exclusive for a few people. If you cannot make enough to get it out to the masses don't make it at all.
Normally I might agree, but this was a big risk for Frost games. There was no guarantee that anyone would buy it. Given the number of different games, the target audience would probably have to own at least 50% of the games. The cost was significant and the size of the package meant shipping was also crazy.
While it turned out they could have sold a lot more, it must have been terrifying to write out that huge cheque on something no one has ever done before.
