You'd be surprised how crazy some people can be. 

It doesn't. And now I'm at the weird portion where I'm unsure if I fall with the type of people who have a "psychological disorder" since Kaluluwa developed an inability to show emotions due to PTSD of child abuse (and PTSD is considered a psychiatric/psychological disorder). Of course I was planning to have a character development using this (either through Gemini or Calming the Soul) so this update is a concern of mine.

In my opinion, it does not make sense for the psychological disorders to not be permitted. The full dive VR system basically just intercepted the consciousness and simulates the 5 senses. Physical deformities are fixed and are able to let amputees use their body parts because the game intercepts impulses to find out if the person would be attempting to move a body part. So if someone was brain dead, they would not be able to play the game as they are unable to make mental decisions out of the basic needs for survival which is to breath and to produce the necessary hormones for daily processes.

Mental Disabilities were focused more MPD than anything else. PTSD is something commonly associated with SAO and the overall theme of the game. Other mental disorders such as Tourrette's, Epilepsy, Autism, Bipolar, Schizophrenia, Bulimia, Deviant Sexual Disorders, and similar disorders are also not permitted. Many of these mental disorders beg the real world question of how and why your IRL character (likely a teen with concerned parents) attained one of the 10,000 copies and a device that is known to specifically affect the mind.

Long story short, if your character absolutely hinges on some mental disability, please make your case with a member of staff and we will evaluate it on a case by case basis.
