Speaking from the experience of a first-time player who has never played any FF MMO.
After playing all three City-State's beginnings, I can say that starting out is a lonely experience for a newbie.
Nobody talks. It seems like everyone sticks to their cliques and guilds and there is little room for a newbie to interact with the server's community. How does a brand new player, with no previous XI or XIV experience and acquaintances meet people to join these wonderful linkshells and guilds?
The other effect of the apparent clique-ish silence is that it makes the game seem like it is dead, even though there are players all around.
Is there a specific point in the game that I have not reached yet where people start talking and being social?
Luckily there is a fairly simple solution to this: automatically place new players in an "Adventurer's Guild" npc linkshell for their starting city. That will more easily put us in contact with one another.
