So I promised that list and here it is. It's late and it's not as thorough as I'd hoped. I also wish I had images handy to illustrate every point where helpful. So, in no particular order - a subjective set of desired features for Fallout 4:
The game takes place in Haran, or “the Immortal Land,” during a period of growing dissonance. Centuries before, a heroine named Trieste had saved Haran from an event known as The Corruption by sacrificing her own life and sealing evil beings known as the Pitborn back into their own realm along with their master, Abaddon.
Now, with Trieste’s magic wearing off, the seal is breaking and the Pitborn threaten Haran once again. And, as before, the people of Haran are forced to fight.
