>>714506756 (OP)Since Fallout 4 was going all-in on guns being modifiable, having as many guns became impractical and had less gameplay use.
In New Vegas, and to a lesser degree Fallout 3, you switched guns as you progressed through the game.
In Fallout 4 you upgrade the guns you have.
I prefer the New Vegas method, because more guns = more cool, but there was a method to Bethesda's madness there.
