Well the Mojam came and went with $458,247.95 raised for charity - a good thing.
I watched some of the live streaming and was entertained by the process of putting the 3 games together. That said, the live footage would have benefited from greater focus and more of a running commentary from those involved.
Mojang's game "Catacomb Snatch" saw several builds released over the weekend, with each one adding significant new features, and the end product being fully playable if a little simplistic. The source code has now been released and a small community has emerged fixing bugs and adding new content.
See Uber Catacomb Snatch
for a compiled fork of the code, and Catacomb Snatch on GitHub
for a repository of community developed source code.
Wolffire have also released their game "The Broadside Express" along with the sourcecode. This one seems far less finished to me, but again there looks to be a small community who intend to develop the product.
Oxeye have yet to release their game.
Overall I do not regret contributing to the Mojam, but I do feel a little disappointed - it is of course better that the games are open sourced so that they see further development, but now that they are out in the wild, what did I actually get for my donation? Not the product, not the live streams (they were accessible to all) - I guess just a benevolent feeling.
