What is there in ghoulification that makes it so wanted feature? If it doesn't have some significant gameplay impacts other than skin color and slightly adjusted dialog options, it's - imo - just a waste of developement time. And with the time Obs has, I'd rather they focused on polishing the core elements instead of tacking in some fruitless features like that.
Just my 0.5 cents.
Good points. Though here's one or two advantages to being a ghoul:
-Automatically get an enhanced Cannibal Perk.
-Never attacked by Ghouls unless provoked.
-Possibly not attacked by Super Mutants (In FO3, a ghoul human mentioned they "leave us alone".
-As a Feral, you'd be an evil character, so anytime you enter a town, attack everyone as though you entered enemy territory. As a human Ghoul, there'd be some tolerance as in FO3.
-You could start out a normal human from the vault, but eventually change into a talking ghoul (radiation poisioning unchecked for too long).
-Unless you curb the radiation levels, you'd slowly change from 'human' ghoul, into a Feral Ghoul or a Swamp, Reaver Ghoul, etc., which would enhance your strength, but decrease your intelligence, making most weapons useless.
Beyond that though, being a ghoul is more of a novelty than a fully functional character, unless they change up the rules of what a feral ghoul could do.
It wouldn't be hard for them to take a ghoul human character and map those options into the create a character intro.
