Problem is that it dont work just for killing citizens but for attacking them , every atack=-karma.Thats stupid .So VC citizen can kill you, but if you attack him , you have problem with VC.And why i cant be protected by NCR or other cities ? when you can be protected by VC?
join NPC factions and you will be protected. Ncr faction is being developed as i heard so wait.
And i think most of you played f2, you should know that vc is likely to invade gecko and enslave them, they also accept slavery as good thing, so even though they are high advanced technologically community, they shouldnt see things bad if one of their citizens kill some noobs they dont give a fuck about :>
