OCD has always been a huge obstacle for me when playing video games, probably more than Tourette has.
I was going to list the games as I did in my Tourette when Gaming article, as tics, intrusive thoughts and compulsions all occurred at the same time. Instead I will list the compulsions and themes that affected me the most as a huge part of the problem was rituals leading up to playing the games and not in the games themselves.
