The game actually went live three days ago but that was just early access granted to those who had pre-ordered the game. ArenaNet and NCsoft confirm that more than a million fans had pre-purchased Guild Wars 2. In order to get an early start, over 400,000 players were registered online all the time. The developers exclaimed this to be a record breaking number.
Brien, President of ArenaNet commented on this milestone calling it a reward of a five year long journey:
This is the culmination of a five-year journey and to be greeted by this level of enthusiasm by our fans is truly amazing. But really our work is just beginning. Now our focus is shifting to building on this living world we’ve delivered, continuously refining our game and improving services to ensure our players have the best possible experience.
Guild Wars 2 is a one time buy MMO and is available now for the PC.
