I'm thinking about making a mod that will add an NPC with an Obsessive Compulsive Disorder and I need your help to think of rituals that I can force it to perform.
Got any ideas?

Well, becuase I have OCD, maybe I can be of some help. One common OCD is humming, but that might be hard to add. Hmm, well, some people steal on a regular basis, taking things they don't want or need. Another is Lieing, but once again that might be a little hard to add in. Oh! One is pacing and constant movement, which wouldn't be too hard.

well most of the common OCD rituals are checking to make sure their door is closed and locked, washing their hands, setting up their dinner plates perfectly, etc. However, really anything can be a ritual. I just saw a show recently about it and if this one girl bumped something with one of her legs she needed to turn around and touch her other leg to it as well.

Lol, I think I have OCD... I always have to count the steps i walk on up the stairs

you are a genius
