I do think this brings up another interesting discussion of the differences between putting together a collection and running a jam. I feel like the former presents a more comprehensible product in some ways, but the latter means you'll get input from people you probably wouldn't reach out to normally.

The other major advantage of a jam as opposed to a collection is, a jam presents the opportunity for spontaneous design--something I noticed a lot of during the Sad Mech Jam. People who said "oh, these games are cool, what about a game where..." and then made a game. That's something you couldn't really get making a collection, and something that I think is really valuable to the community/hobby as a whole.
