Guild Wars 2 is unlikely to have any expansion pack, according to Eurogamer.
The original Guild Wars launched in 2005 with no monthly subscription, an idea that moved away from traditional MMO thinking. The way that the game paid for it’s upkeep, and managed to make money, was by releasing paid for add-ons and an expansion pack. Lead content designer Mike Zadorojny has said that the trend probably won’t continue this time around, “So right now we’re not really looking at expansions as an option.”
Instead of the expansions ArenaNet are attempting to add content on with the Living World which basically means more content, more quickly. Four teams work for four months creating one month’s worth of content. “So they’ll own two content releases in a particular month,” Zadorojny said, “This allows us to have this world that’s changing and evolving and essentially goes into what television does: stay tuned next week when something exciting is going to happen.”
Guild Wars 2 doesn’t require a monthly subscription either so ArenaNet are confident that sales of the game, and micro-transactions within it, will create enough cash to keep the game running.
