Well, I understand that it's a great honor, and a pretty big deal to win so many awards, but who of us are really surprised by this news. In any case, some of the awards Guild Wars has won this year are:
ArenaNet for Best New Developer by Voodoo Extreme, GW in Top 5 Games of the Year by Voodoo Extreme, placed in IGN's Best Persistent World Game and Best RPG categories. Finally, Best MMORPG of the Year and one of the Top 10 PC Games of the Year by Gamespy.
