I can remember, there was a likely idea, just with the difference, that he or she wanted nationality Fractions (or something like that, I can't remember exactly). Mojko meant it would danger the whole peaceful atmosphere in the forum and in the game and I have to agree!
But that's not a matter, why there are no Clans/Guilds or Factions, I don't know if someone wants that, but I think it would be really interesting, especial with the Team-games…
There's just one thing, which destroys the idea a bit: The number of players; it does not make really sense, if there are so less players... (I don't know the number of active players)
