You hear who is near you
Stand next to someone and you hear them clearly. Walk away and they fade out. Past the range you are speaking at, nothing.
Choose how far your voice carries — 5, 10, 25, 50 or 100 yards — so a whisper across a table and an address to a crowd are different acts.
It is positional, too — a voice comes from the side its owner is standing on, so a crowded room sounds like a crowded room.
Nobody knows your name
Everyone reads as their race until they choose otherwise. A stranger is a human, a tauren, a gnome — not a name you have already read on a nameplate.
Right-click and introduce yourself when you mean to. Names are something you give, not something the interface hands out.
Strangers are known by a name of their own — the Hooded Orc, and the same one every time — so people can talk about someone they have never met. Introductions run one way, too: telling someone your name does not get you theirs.
A world with consequences
Town notice boards take real bills — work offered, warnings posted, debts named. Anyone can read them and anyone can answer.
Violence is something you consent to. Flag yourself an outlaw when you are open to it, and live with what that invites.
Lawmen are appointed by name, wear their city's tabard, and carry a Writ of Accusation and a set of iron shackles. Being arrested is a scene someone plays with you, not a respawn timer.
