We like our detail to be in the towns and factions, not in the little terminal or skeleton here and there.
And I think thats where part of the problem is.
I liked in Fallout 3 where I could build my own details based on what I found in the world around me, heck I bet I could write a fan-fiction on a skeleton I found in a metro, and I found I couldn't do that in New Vegas, as the (great) story was directly told to me, rather than me forming it myself.
Don't get me wrong, I like towns to have stories behind them and such, and I find great fault with Fallout 3's storyline, but as you can see, the relative lack of those things didn't bother me when I played 3 to the extent that it did others, and I sorely missed the atmosphere that Fallout 3 exploration brought to me, and its part of the reason why I will likely never get as much out of NV as I did 3.
why would that stuff even still be around? after 200 years of scavengers? most people in the Fallout world don't really care what happened before the war, they are trying to survive the hear and now. that's was one of the things that broke the games worlds continuity for me. If places still had power, or working old world tech in the Originals it would have been scaved or reposed right away and you'd see nothing left of the old world users. they set the world up like it was only maybe decades or a few years after the bombs. Everyone is still wearing pre war clothing, and knows something about prewar history it seems.
I never looked into that "200 year old factor" as much. Fallout 3's setting was logical enough for my tastes (and I think many F3'ers would agree with me on that), but I recognize that it cleary wasn't enough for others.
Its a matter of preference really.
