Do you like killing a seasoned wastelander, who's carrying a sweet gun he's used to conquer many foes, thus making it your own?
Basically, do you like your own modded weapons, or unique weapons? Personally, I can't let my scoped hunting rifle go. Even at level 50. I have the other too modds for it too, but I think one of the best things added in New Vegas was weapon mods.
Don't get me wrong, I love unique weapons, and have made it my own little quest to acquire all of them, but there's something about weapon mods for me.

Woops! Forgot to add the poll xD
