This year NaGaDeMon seems to be getting a decent crowd of participants.
I've already put my hand up with the intention of getting a finalised second edition of Walkabout into people's hands (the first edition was created for Game Chef 2010). I'm hearing a few good things about some of the other games that people are intending to produce.
For everyone who is participating, good luck.
For those who aren't, go and have a look at the Google plus page or the Facebook group. They seem to be the two places where the action is focused.
