I've played New Vegas for a while, and I was wondering, is a Melee only run as feasible as it was in FO3? The enemies now have the armor effects, which seemed to make using anything other than a gun a bad idea, and it takes a while before you get any armor piercing fist or melee weapons. Should I just stick to guns? And if a close range only character can be decent, anyone have any good chracter builds?
