who the forget would be default lol that's so boring
I personally wouldn't, but apparently some people like to, because it's the face that the game devs designed for the character.
But really, it's just a plain generic face.
I'm going energy weapons as much as possible, I think.
Hopefully you're able to get to using them fairly quickly, compared to New Vegas, where there's that laser pistol at the beginning, but then all your enemies will forever be using shotguns and rifles.
So yeah, hopefully you can get ahold of an energy weapon, and then ammunition isn't too sparse for it.
I'm hoping that thematically it shouldn't be, given the advanced nature of the Commonwealth.
