It Wandered In From the Wastes
The specialized round system in NV (which grew from 1-2) is great. It means weapons can't just become incredibly out-classed against armor, and adds another layer of strategy. For most it meant AP and hollow points, but there were also cheap rounds to save caps (surplus, .38 special, ect), the 10 types of specialized 12 gauge ammo, 4 types of missiles, multiple types of propelled grenades, min-nukes, ect. All around good system that was also quite intuitive, so that nobody would have any trouble with. I can't think of any reason it wasn't implimented besides laziness.
