"Over time, our focus has shifted to updates that not only help maintain Guild Wars but help the game maintain itself," ArenaNet posted. "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!"
Tournaments, events, and birthday prizes will be moved over to automation during this transition. The studio said that automating the game will keep it running longer and that it will keep a live team on Guild Wars to handle critical fixes and troubleshooting.
