If you're interested in attending the show and missed your chance to register online, don't worry! You can still register onsite next week.
The GDC registration desks in the North Hall of San Francisco's Moscone Convention Center will open this Sunday, March 1st from 5-7 PM PT to afford conference attendees an opportunity to register early and claim their badges before the conference kicks off on Monday morning.
The registration desks will open again bright and early on Monday, and remain open during select hours throughout the show. If you haven't purchased a GDC pass yet, you can stop by any time the desks are open (check the GDC website for exact hours and location) to buy one that meets your unique needs.
For a better idea of what you're paying for, all announced conference sessions are available for your perusal in the online GDC 2015 Session Scheduler, where you can begin to build your conference week and later export it to the up-to-the-minute GDC Mobile App.
Again, GDC 2015 itself will take place March 2-6, 2015 at the Moscone Convention Center in San Francisco, California. You can register for the event by visiting the info page on the official GDC 2015 website.
