Automated Tournament Series to Continue into 2008

We are extending the Automated Tournament Series into 2008 with a number of improvements. For the first part of the series we will offer electronic gift cards from Amazon.com, allowing winners to select their own prizes from Amazon's vast catalog of products.

April marks the third anniversary for Guild Wars, and we plan to commemorate this event with a special anniversary tournament that will feature an expanded prize pool. After this concludes, we will transition from real-world prizes to exclusive in-game awards, including never-before-seen items. Rules for the 2008 Automated Tournament Series can be found here, and details about the in-game prizes will be released in the spring.
