Realy? Effecly North Vegas need more. have you some ideas about this?
Would be fun with a giant rat hunting quest.
Nothing major.
No big exp deal.
Just a quest to show that the people are really poor and need to live off of rats.
And if one kills a lot of them they get all like "Ooh you got so many of them! You're an awesome hunter!".
To them it's a big deal.
To us, maybe not.
But to them it means food for another day or two.
Course, the evil option could be to force them to buy it for additional caps or heck if you're feeling really evil, poison the rat meat.
Then maybe have a junkie completely out of his mind which if you tell him you have drugs he will attack you if you don't give it to him.
Again, nothing major, just there to give flavor to the area and show a junkie that is desperate to get another fix.
A way to help him is to direct him to FotA or give him fixer.
The bad way could be to give him lots of caps so he over-doses on the amount of drugs he buys, give him tons of drugs directly and let him over dose in front of you or tell him he'll get drugs/caps if he kills someone in that area for him.
Stuff like that, except maybe less black and white as I put them.
