In a post on the official site, the studio stated, ”Over time, our focus has shifted to updates that not only help maintain Guild Wars but help the game maintain itself. With this focus in mind, we’ll no longer be releasing any new content for the live game except in support of automation. Our goal is to get the game to a place where it can continue to run and be available to all of our fans. We have a lot of love for Guild Wars — it’s the game that made us what we are today — and we want to continue sharing it with everyone!”
The MMO had a strong 8 year run, but naturally Guild Wars 2 has overshadowed it. A team will be available to the original game if the game has a catastrophic crash or issue.
