Sponsored by YouTube, the award recognises six of the top gaming video series for users to vote on. The shortlist includes The Yogscast, TheSyndicateProject, Total Biscuit, AtheneWins, Matroix and InTheLittleWood.
Voted exclusively by the public, the GamesMaster and HMV sponsored awards are entering their 30th year.
New categories this year include 'Best Downloadable Content', 'Top Gaming Moment', 'Best Mobile/Tablet Game' and 'Best Browser/Flash Game'.
Meanwhile, returning categories include 'Best Handheld Game', 'One To Watch', 'Ultimate Game of the Year' and 'Best Action Adventure Game' (in association with Digital Spy).
The results will be announced on October 26 at an awards ceremony in London hosted by comedian Ed Byrne, and the event will also offer exclusive reveals of new titles.
Users can cast their vote for the YouTube Gamer Award on YouTube, and can still vote on the main award categories on the Golden Joystick Awards site until October 22.
