As many who attended GDC recover from illness (thanks to days of rain and the plague-ridden in attendance), CMP Media says its 2008 conference broke a record and hosted 18,000 game industry professionals (previous attendance was somewhere around 16,000). Highlights included, well, we've covered all that already. GDC will be back at the Moscone Center in San Francisco again next year, blissfully later from March 23-27.

Attendance could also take a tiny dip next year as Kotaku reports GDC may become invite-only for those seeking press credentials. Jamil Moledina, executive director of the Game Developers Conference, tells the site that CMP hasn't nailed down details on how it's going to work, but they are looking at an "invite model for press access." Moledina is worried about maintaining the show's atmosphere and wants to make sure GDC maintains its core goals.
