Personally, I want to be able to Traditional Chinese text interface because:
NO.1) I can fully understand the content of the main story of each race.
NO.2) I can completely understand all the “love mission” and “dynamic events” the story content.
NO.3) I can fully understand that the NPC on the side of the road in what to say about their story.
All in all, I hope that Guild Wars 2 is a game I can play for life, thank you very much.
