I realize that at their core dollar stores are bad for communities.  Building a game jam concept around dollar stores isn't an endorsement of the economic system that supports this kind of retail. What it does endorse is the idea that the current model of tabletop game release is fundamentally financially inaccessible to a significant portion of the public. Hobby gaming (like many hobbies) is class segregated and until we move to break down the models that tie play to consumption we can never be truly inclusive.

Interesting points you got there, but what about thrift shopping, buying dirt cheap goodies from china, and even 3D printing? For example, you can get polyhedral RPG dice for only a few bucks online from China, you can also chess & checkers dirt cheap from Dollar Stores, which can total up to about $5 if lucky.
