What was Mystery Prize 2 going to be?

[Dragon Star]

Rich said he had an idea for it that turned out to be unviable economically. What was that idea?

Personally, I think it was to send a blow-up punching bag (or kicking bag) shaped like Belkar to every pledger.

[factotum]

Pretty obvious it had to be sending something physical to each pledger, since that's the only way I can think of that would increase the costs to the point of it becoming unviable...
