Guild Wars 2 has reached number one in the official charts of ten countries across Europe, NCsoft and ArenaNet have announced.

Released ten days ago, Guild Wars 2 stands at No.1 in the official All Formats charts of the UK, Germany, France, Spain, Denmark, Sweden, Norway, Finland, the Netherlands and Belgium.

"Our games have always been well-received in Europe, but this level of enthusiasm is both awesome and humbling," said Mike O'Brien, president and co-founder of ArenaNet. "It also impresses upon us the responsibility we have to our players and explains why we've taken steps recently to constrain sales of Guild Wars 2 to ensure the highest quality of service. Of course, we hope to remedy this in the near future."

The game is said to have been "flying off the shelves," with the Collector's Edition box proving "extremely popular".
