Don’t get me wrong… I would love to see my “Alter Ego” in the game. Actually I have a sweet little idea how to make this happen, but that’s another story 
. I also would like to have the option to run around through the city I am building. My comments are more related to the idea of building your city from a 1st person view (as this was my understanding why you have created an own thread and not continued to discuss it in the other one).
Maybe your idea could also be merged into this discussion on a “Leader”, “Chieftain”, “King”, whatever. This could be also a representation of yourself, no?
