Guild Wars 2 launch, and that means that time is becoming very important. If you're desperately trying to get a specific name on launch or just aiming to be ahead of the curve when you play, the exact times that the servers come online will be very relevant, which is why there's a new official post explaining exactly when everything is happening on the road to a full launch on August 28th.
Pre-purchasers with access to the headstart will be able to start playing on August 25th at 3:00 a.m. EDT, with the caveat that servers may be brought up three hours early to check stability one last time. Those who pre-ordered the game but didn't fully purchase a copy will have access to a one-day headstart beginning on August 27th at 3:00 a.m. EDT. If you're in either camp and want to get patched up ahead of time, you can download the client now and ensure that your computer is ready to catch every moment of the last two weeks before launch.
