ArenaNet has announced Guild Wars Afterlife, the first major gameplay update for the original Guild Wars in nearly 20 years, per Eurogamer. The studio is building it alongside co-development partner 2Weeks.

It is hard to overstate how unusual this is. The original Guild Wars launched in 2005 and has spent most of the past two decades in maintenance mode, kept online as a quiet gesture to its community while ArenaNet poured its energy into Guild Wars 2. Live-service games from that era rarely survive at all; getting substantive new content is rarer still.

The decision to bring in a co-dev studio suggests ArenaNet wants to expand the classic game without pulling its core teams off Guild Wars 2. It also signals that the publisher sees real value in the original's enduring player base — a community that has kept logging into Tyria's first incarnation for two decades on the strength of its distinctive skill-based, instanced design.

Details on exactly what Afterlife contains are still emerging, but the name alone — a major update for a 20-year-old game most assumed was content-complete forever — is the kind of announcement that MMO preservationists will be celebrating. Sometimes the old world gets a second life.
