I plan to play with Mod, and He is my Aunts Husband. so was wondering what he would call me. Not native English speaker. I call him Uncle and he calls me?
Have not played in a while but there is a scene where Uncle says to MC "I love you like a true son". He also refers to his brother (MC's father who has died apparently, before the game starts). Just done a bit of a play through and Uncle does not really refer to MC by "name" or as relation type eg nephew. In the relationship screen ordinarily you would put "Uncle" and "nephew".
Aunt on the other hand calls MC by "name" or as nephew.
I will add that playing with a mod to change relationships, there are times where the story does not make sense.
I modded the script to make sense it changes the relationships to family.
Here. Will not work with other mods.
