We have just been notified by ArenaNet that they are going to be holding an unprecedented event during the 2004 E3 event. If you are not sitting down - you might want to do so now...
They are going to be allowing EVERYONE to play a small demo version of Guild Wars online. This will only be during the 3 days of the E3 convention and they will be making the client available as soon as 2 weeks prior to the event. The download will only be around 30MB...and will be available on May 1 from the new GameSpot DLX service.
You can get more information at the GameSpot site at this link.
