There is nothing to do at them. Zero quests overall. You'd think they would be teeming centers of the game given they are the centerpiece. Instead they are ghost towns and feel vacant, empty and artificial.
No where in New Vegas am I more reminded it is a game and immersion broken then when I'm on the Strip.
Freeside is chock full of quests that flesh out the area and its inhabitants... in fact, it feels more like the Strip to me .... quests to be muscle, to help a crime family, the tension between NCR and the Kings....
The Strip??? Empty. Desolate.
It makes me angry and sad every time I play the game. It's like the devs figured: here's eye candy, they won't notice that it is all light and shadows with no substance.
Sigh.
