Found this on 4chan or something a few weeks back.
Alright, figured out how to do it because Save Words aren't a thing anymore. Still just as effortless.
On the latest build, after you start a character a file called FSCharacterSave.GLKData will be created. Save your game to create the file then close it to prevent shenanigans. Open FSCharacterSave with wordpad or at least something with a search function. The baseline states for a new character is 17 12 12 12 12 12 if you put your starting stat bonus in strength. Just Ctrl+F "12 12 12" or some shit.
Those are your six stats. In order: Strength, Dexterity, Stamina, Charisma, Perception, Intelligence.
Change all that shit to 200. High enough to one shot dragons with your barefists and more than enough to meet the stat requirement for every perk in the game, but low enough to play nice with stat calculations. Save the file, and open the game up again restoring your save. You'll be a freshly born lad/lass who's /litfit/ like Zyzz and Steven Hawking's love child, and ready to get their Chad on with any wasteland critter who looks like they need some fuck.
Just remember to ward/ban any fetishes you're not into during character creation beforehand.
