[The Experimental Gameplay Sessions at GDC, organized by Jon Blow and compatriots, is often one of the highlights of the show, and packed to the gills, so we thought it would be good to highlight his call for submissions for those doing... different stuff.]

The organizers of the Experimental Gameplay Sessions lecture at the 2009 Game Developers Conference are calling for submissions for their yearly showcase of innovative games.

This regular extended GDC lecture, which has taken place since 2002, is organized by Braid designer Jonathan Blow and friends.

It's notable for being an early showcase for a multitude of alternative games and game concepts, including a pre-launch Katamari Damacy and Portal.

As the official Experimental Gameplay Sessions website explains while issuing its call for submissions:

"The Experimental Gameplay Sessions are an annual gathering of innovation-minded game developers, hosted at the Game Developers Conference in San Francisco.

The EGW features many different kinds of games, including prototype demos (such as the Indie Game Jam games), [subsequenty] shipped products (such as Katamari Damacy and MojibRibbon), and student demos. There’s always a bit of lecturing and discussion as well.

If you’re pushing the boundaries of traditional gameplay, we encourage you to submit your work using the entry form. The submission deadline is Monday February 16, 2009."

Other notable projects showcased in early stages at various iterations of the Experimental Gameplay Workshop include Jon Mak's Everyday Shooter, Thatgamecompany's fl0w, Media Molecule co-founder Mark Healey's Rag Doll Kung Fu, Zoe Mode's Crush, and Dylan Fitterer's Audiosurf.
