Why A guild? I realy don\'t see many advatages to the (virtual) life in a guild, sure, thare probably be some but there will also be disadvantages...
I, for one, won\'t join a guild... there will probably be, beside guilds, groups of \"friends\" in the final game, who can help one another...
Maybe that one day I will help some guild members of one guild and another day it could be a member of an enemy guild...
And if the game will be PvP, I don\'t think that there will be many people that will kill a single person with a group (or am I wrong, I hope not

)...
