From what I heard from community, Xodarap777 stoped modding Fallout games. As a huge fan of his XFO mod, it was disasterous news for me. But as other friends have said here, Arwen's mod looks promising. I was using some of ART modules along with XFO in F3 and her new version for NW also looks but. However we may need to wait for a while before she completes that mod because it is in very early stages. I tried it out and saw that there is a lot of work to be done.
Yeah his looks ok but after playing XFO's, I just can't seriously consider a 'realism' mod that doesn't change the points to affect accuracy and not damage. I could have never picked up a gun in my life or I could be the effing Punisher but both picking up guns and shooting would never have any impact on how much bullets hurt....only maybe the likelihood of a critical hit. Noob gun shooter hits someone in the chest in the lung, Punisher hits someone in the chest twice in the heart.
And I've tried Hardercore and so far it needs a wee bit of tweaking but I like it.
