This is a quote from EGX 2014
Question:
I'm going to act as The Voice Of The Internet and be Twitch again. And someone asks: Will there be a Corporation, Guild, or Clan System, within Elite: Dangerous?"
David Braben:
"Right there is the, sort of friend's alliance, ehm but at least to start with we've not got Guilds and Clans. Ehm, I think what we don't want is this... this... the whole game to become ossified very quickly, where the... y'know you have to join one or the other to have any fun gameplay. I do like... essentially it's the game of the freedom of the individual, the ability to just go out and do your own thing. Ehm, y'know the... guilds can very easily become almost like Mafiosi saying 'Don't travel here or we'll kill you'. So, um, I think it's something we will look at and are looking at, ehm, but friends groups which are very much more constrained, I think are great, but then when it gets much beyond that it becomes a bit... it doesn't feel right."
He doesn't sound keen on guilds to me, perhaps he suspects they might try to use "Mafiosi" style underhand tactics (for example trying to adversely influence polls).
