In losing the monthly fee ArenaNet have given themselves the freedom to excise the MMORPG’s accreted dross: the subscription-prolonging treadmill, the trickle-down economics of fun that says that only your elites have paid enough to get to see the cool dragon. Then, that spirit of change has passed through every other assumption that MMOs make about themselves and their players and touched each in turn. Nothing is ever so fixed that it shouldn’t be broken and remade. It’s not perfect, but it is ideologically and structurally sound in a way that few MMORPGs manage at launch, if ever.
Guild Wars 2 is not a revolution, but it is a call to arms. Tomorrow’s MMORPGs will be held to account against its standards: generosity, variety, and respect for the player’s ability and time. Of course, by that point, it won’t be Guild Wars 2 waving the banner. It’s not a revolution. It just quietly suggests that we start one.
