Okay, so we're starting from the (almost) very beginning here: we know that we have a city, but not a real one because we're not from the same area, so basic geographic features need to be filled out. Like coastal, not coastal, rivers, etc. Big stuff. I'm in favour of having a subway.

And what type of game it should be. I'm guessing not a philosophical rumination on the nature of good vs evil or human vs monsters.
