While FO3 and NV take places on opposite ends of the old US, have any of the characters endeared themselves to you enough to want to see them again?
Would you like to see certain characters from FO3 or NV (or even the originals) come back? If so who and why?
IIRC the lore says that Harold's tree (Bob) bore fruit; It seems plausible that it could produce seeds... What if those seeds, when planted, grew into semi-sentient trees with sporadic copies of Harold's memories and identity... In effect plant-clones of the original Harold that believe themselves to
be Harold.
What if the original Harold actually settled somewhere back on the West Coast?
Bethesda's Harold is something I could live with being totally 'retconned' out as a bad judgment mistake.
