According to lead content designer Mike Zadorojny, it is feasible for the original Guild Wars to continue running forever thanks to automated support features added to the game.
"We've been doing a lot of automation support so that the game itself could last forever, even without anybody really touching it," said Zadorojny.
"They're not necessarily making new content right now but there is a team that is monitoring if there are massive issues they're taken care of, and they're supporting them."
Zadorojny added that there is still an active community in the original game, which ArenaNet has no intention of abandoning.
"The game itself was so efficient on the server side in terms of the resources, like, it runs on a fraction of the hardware that we need for running Guild Wars 2, so having that on the back-burner is nothing compared to GW2.
"There's still a community there that's really passionate and really thriving in there, so we want to support them as best we can."
Guild Wars first launched in 2005 followed by the release of its sequel in 2012.
