Really? I thought they were much more integrated in NV then in Fallout 3 at least... All those ghouls working with the NCR - Keely, the doc at Aerotech Office Park, Beatrix, ghoul rangers,
really makes you sick *mumbles*. In FO3 Underworld was like a ghoul ghetto, they didn't really try to socialise with humans.
Also a lot more relatively 'friendly' supermutants in the Mojave, compared to what - Fawkes, in CW?
Also, if anything, the Wasteland needs less mutants of all types, but that's what I'm there for...
