For those cake sceptics the basic premise of Molyjam is to pick a game idea from a list and do as good a job as you can with it in 48 hours. The twist is that Molyjam gets its list of ideas from @PeterMolydeux, a twitter parody of Peter Molyneux, and the ideas are all colossally bizarre.
I'd love to do something like this on here, we could use @PeterMolydeux or we have tonnes of ideas right here on the forums that never got made for some reason. Anyone else interested in this?
