Great MCA has graced official F:NV site with his majestic words in form of a developer diary<blockquote>As hard as building a new world can be, it's an equally hard task to figure out what elements to draw from the past that you want to resurrect in the present. In many respects, it's a challenge that one of the leading figures in New Vegas is still dealing with. And, the pluses and negatives of this should be apparent when you travel to the city of New Vegas. Maybe not all at once, but over time... it'll sink in.
There are issues with domesticating tribals and forcing them into one view of the world, there are issues with treating a wonder of the old world as nothing more than a bloody battleground, there are issues with propping old flags from Rome and California without a clear understanding of what those flags represent, and the long-range perspectives of many characters you'll encounter in the world have strong opinions about what's going on in the present, all born from the elements above. The question of the Old World making itself heard in the present - in the Mojave - is a core theme in Fallout: New Vegas, and whether overt or not, we hope it sinks in with the player as well.</blockquote><center>
