Developers, the organizers of the perennially popular Experimental Gameplay Workshop have issued a new call for submissions of experimental video games and game prototypes. The more interesting or offbeat they are, the better. Selected titles will earn a slot in the two-hour Experimental Gameplay Workshop session at GDC 2015 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, this year's workshop is once again being organized by Robin Hunicke (Journey) and Daniel Benmergui (Storyteller). The workshop affords developers from all over the industry a chance to show off concepts that push boundaries and potentially expand the scope of the game industry. 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 Guitar Hero, Katamari Damacy, Passage, Spelunky, Portal 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 2015, check out the official submission guide on the EGW website. If your prototype is selected for the EGW you'll also receive a full GDC 2015 Speaker Pass, allowing access to the entire conference. This call for submissions will remain open until 11:59 PM Pacific on Saturday, January 10, 2015. The Experimental Gameplay Workshop itself will take place Friday, March 6 -- the final day of the 2015 Game Developers Conference, which runs March 2-6 at the Moscone Center in San Francisco.
