That's how you know its working.
OT: Like the Colonel I am also not a six-yearning teenager/desperate, but I can also see that they are in Fallout for the same reason that chems and cigarettes are: its realistic. As with any addition to Fallout, the final moderator I listen to is this: "does it make sense?". It makes sense for New Reno, New Vegas and other similar cities. It does not make to sense to have them walking around Modoc, Rivet City or Novac.
This!
Fallout 3 didn't have strippers, at least none that I actually remember and they really was no need for them.
New Vegas, Strippers added to the "atmosphere" but mainly made me laugh. "You like what you see?" OMG hahahahaha ok anyway, yea. Plus, I think who ever is talking about the screen black out, you are NOT talking about strippers... LOL
But yea, don't just throw them in for the hell of it. It's with everything when it comes to world building and adding NPCs. The Devs have to ask:?
Do they fit the area?
Do they make sense in that context?
Do they add realism to the world?
Stuff like that.
