The good folks at QGCon at UC Berkeley need YOUR session proposals for their third year running. I participated in the first year it ran, 2013, and I enjoyed the mix of scholarly rigor and casual atmosphere, there a pleasant mix of academics and not-academics that's very refreshing.
You can be a super academic-y academic and present a paper, or you can talk about a game you made, or discuss a specific games community you're part of, or even relate your personal experience with games and/or run a workshop. They're pretty accommodating and welcoming and supportive, even if you've never given a talk before. It's also pretty unique, there's really no other conference on the circuit that even tries to approach these topics.
I highly recommend submitting a proposal by July 1st, especially if you live around the Bay Area or along the west coast, it's just a short trip over.
Here's an excerpt of the call:
