According to several online sources, ArenaNet has confirmed that Guild Wars 2 players will be able to join more than one guild. All characters will belong to the same guild(s) but players can use characters in different scenarios within different guilds. If today is Monday, it must be RP guild day!
The guild information released was:
- Guild membership is account wide, and you can add as many guilds as you like. You will be able to choose, at any time and on any character, which guild chat you are viewing and what guilds you are currently affiliated with.
- Doing different activities (“almost anything,” to quote Eric Flannum) with guild-mates will earn Influence for one’s guild, which can be spent towards guild upgrades (storage, etc), or special in-game boosts like a flag that grants extra XP to guild members within its range.
- Specific guilds will be able to capture keeps within WvWvW PvP, and be able to use their Influence to create upgrades to those keeps.
