As Tim says, the pilot group was caught rather off guard by the question,
and in the hysteria of, "Oh, we have a Collectors Club," and "Cool, we can decide what items could go on DS?!"
We were fairly unprepared to deal properly with it.
During the aftermath of choosing what items we wanted, we discussed a few ways of making sure we did a better gob next go round.
One of the biggest concerns was that there seemed to be mostly Medieval collectors...
Which is why there is somewhat of a lack of other themes, or of very different themes.
Part of our discussions was on this subject, and how we would correct it in future.
