It's that time again: the organizers of the Experimental Gameplay Workshop have issued a call for submissions for fresh video game prototypes. The more offbeat or experimental they are, the better.

Selected titles will earn a slot in the two-hour Experimental Gameplay Workshop session at GDC 2014 in San Francisco, which aims to showcase an eclectic mix of unusual game concepts that explore new ideas and genres.

According to the EGW website, organizers include Robin Hunicke (Journey), Daniel Benmergui (Storyteller), and Richard Lemarchand (Uncharted). The workshop affords developers from all over the industry a chance to show off concepts that stretch boundaries and -- hopefully -- move the industry forward.

In fact, a number of "experimental" titles that have been part of the EGW in years past have gone on to become some of the most well-regarded games in the industry. Standout examples include Portal, Katamari Damacy, Braid, Spelunky, and more.

To submit your own experimental prototype for this year's workshop, you must have a playable build of your game ready for consideration. For more information on how to put your game forward for EGW 2014, check out the official submission guide at the end of the announcement.

It's worth noting that if your prototype is selected for the EGW you'll receive a full GDC 2014 Speaker Pass, allowing access to the entire conference.

This call for submissions will remain open until Tuesday, February 4, 2014. The Experimental Gameplay Workshop itself will take place Friday, March 21 -- the final day of the 2014 Game Developers Conference, which runs March 17-21 at the Moscone Center in San Francisco.
