The organisers of GameCity have announced that the events in this year's event, GameCity Squared - taking place across Nottingham City over October 27-31 - will be entirely free of charge.
The event will be centred around the city's market square and aims to be "the most accessible GameCity to date".
"GameCity represents a unique platform for the games community to step up as an important part of contemporary culture," said festival director Iain Simons. "We'd like to urge the developer and publisher community to get in touch with ideas, however improbable they might seem."
Last year's event saw activities hosted by Media Molecule and Jonathan Coulton, among others, and the launch of the National Videogame Archive by Harmonix and SCEE.
