GDC Online organizers are reminding potential attendees that today is the last day to save up to 40% on passes to the October 5th-8th event in Austin, TX, fully detailing the comprehensive exhibit floor, Summits, keynotes, a PlayStation Home developer day and more.

The Austin, Texas based GDC Online conference -- formerly known as GDC Austin -- is mainly focused on the development of online games, including free-to-play titles, social network games, and traditional MMOs, with a veteran online game industry advisory board evaluating and selecting the lectures.

There are now more than 120 panels, lectures and tutorials currently scheduled for the event -- including the recently announced keynote from Civilization II designer and now Zynga chief game designer Brian Reynolds (FrontierVille), and just-debuted track keynotes from Blizzard on Battle.net, Raph Koster on social design trends, and European browser game giant BigPoint on its rise to success.

These lectures join a full set of highlighted lectures including Main Conference talks on October 6th-8th from Relic, Sony Online, Carbine, KingsIsle, IMVU, Disney, Playdom, BioWare Austin, Hangout Industries, Broken Bulb Studios, CCP, Gaia Online, Playfish, InstantAction, Ubisoft and a host of other notable companies at the leading worldwide online game-specific conference.

One of the other major advantages of attending GDC Online is the comprehensive list of nearly 90 exhibitors with whom attendees are able to get product demonstrations, meet, and interact on the vibrant GDC Online Expo Floor. These include major firms like Epic, Rackspace, Gaikai, Offerpal, Vindicia, Trinigy, ARIN, Versant, Rixty, Softlayer, and many other notable companies in the space.

Vendor-led sessions will also provide notable takeaway for many attendees, with a just-confirmed PlayStation Home developer day -- presented by Sony and giving full information on the console-based online world platform. Also confirmed are sessions by Playspan, Offerpal, Hi5, Autodesk and a host of other firms in the process of being scheduled and announced on the website.

Finally, the four Summits taking place at GDC Online on October 5th and 6th cover some major emerging areas in the video game space, with an iPhone Summit, iPad Summit, 3D Stereoscopic Gaming Summit and the Game Narrative Summit all presenting major speakers, themes, and takeaway relevant to both those making online games and devotees of these particular submarkets.

GDC Online is operated by the UBM TechWeb Game Network, as is this website, and will take place October 5-8, 2010 at the Austin Convention Center in Austin, Texas.
