I'd just like to see mods that add in a whole bunch of player slavery in a longer sense than what was ever implemented in fallout 4. Some system that makes a slavery experience coupled with a game that is still "playable" in a sense, and not just j*rk off material.
Also I'd love to see one ending where the player is used as a breeder for one of the creature factions (as mentioned in the mirelurk section), or maybe a way for the player to be used as "livestock" for the inventive settlers of the capital wasteland craving some "dairy" products (I.E: forced to drink lactation chems which make them a sex addicted milk cow - needless to say I was a big fan of mods that approached this in skyrim), or maybe even a version where the player is grown for some sort of meat farm, then wakes up in a synth esque body.
Really I should take to modding myself I suppose, but I don't seem to have the time... oh well :') I'm interested to see where this thread goes regardless.
Anyway, these are pointless thoughts, I'm just waiting for my fallout play time to shift to a whole new purpose :')
