Well you cant create your own clothes...
Nor do gun racks...
In the begining the house customization was horrible, if it rains outside it rains inside, it doesnt protect you from the radiation storms, the game engine seemed a bit outdated... It's just the small things you expect bethesda to do they put it in other games but wont do in this one... the dialog wheel is kinda stupid, there's not really a karma system like the old fallouts. The gun customization is fun. I wish there was a more variety of melee weapons and swords & throwin knives....
Like i said for me personally it's the small things...
