Feels like QuakeCon 2008 only just wound up, and here we are talking about QuakeCon 2009. Ah well. That's the slow, inexorable march of time for you, I guess.
The world's premier id love-in will once again be held at the Hilton Anatole in Dallas, Texas. It'll run from August 13-16, will again feature a super-sized LAN party, will again feature talks by id staff and will again be free of charge.
