Out of the Past

Ha! You thought I was going to talk about the cool Robert Mitchum film from 1947, didn't you? Well, actually I just have, so you'd be right I guess.
However, in my noir mmo (just like in this and numerous other cool-azz films) the past always catches up to you.

How would this work?

Here's what I'm thinking:
At some pre-determined level (say level 40/80), a person from your past suddenly shows up and of course has something on you. Depending on how you've played the game so far (on a scale of coldblooded vs. sweetheart) determines how the next series of missions is constructed. For instance, you've chosen to play a Mob character and your mother shows up @ lvl 40 and you've been a sweetheart. She may be like Tony Soprano's mother and demand you to kill everyone at X location. Say you've been a coldblooded murdering fiend, when your mother shows up she only wants 1 guy roughed up a little, and you can't kill anyone at X location.

Who shows up could also be a random roll. As a Mob character there would be 3 possible persons from Out of the Past; your Ex-girlfriend Janice, your mother Eunice, or Tommy 2-Tone, an ex-business partner.
If you were playing a different race, it would be 3 other possible folks from your emerging back story.

All of this hinges on the 1 absolute fact about Los Angeles: Nobody is born here.

So everyone starts the game by getting off the bus in L.A. (or whatever the city name will be). But there is no better name for Los Angeles than Los Angeles.
