Voted No.
I'll echo the point Quadrana made above - this looks to be a complex feature and could very well split the player-base - especially if mega-guilds get formed.
If I owned, or was part of a guild that owned, such a private space I would be much more invested in "my" part of the world...
Hey guys, just saw the Firefall-forum message now and wow this is awesome!
Donated straight away, but I used a different email address than the one on the forum.
Does anyone know if that's going to be an issue further down the line or if we can just add a game code or something ?
