Guild Wars 2 may not have a subscription fee, but the base game still costs money. If you've been on the fence about dropping $50 on a new MMO to play, ArenaNet's giving you a chance to try it out first. A free trial weekend has been set for August 23, and registration is now open.
All you have to do is head over to the official Guild Wars 2 site and fill out a form. The only credentials needed for a free trial account are your name, email, password, birthdate, and display name. After that, you should be able to download the game client.
Note that the free trial will begin August 23, 12:01 AM PST through August 25, 11:59 PM PST. Better free up some time between then.
Apparently, Guild Wars 2 has been named the fastest-selling MMO in history, based on both physical and digital sales. Gotta love that "no subscription fee" thing.
