Plants vs Zombies (PvZ)-Syndrome

When playing the videogame "Plants vs Zombies" or its sequel. The PvZ-Syndrome can occur. It is the feeling you get, when completing a level and all of your Plants are placed symmetrically on your yard. It can be experienced by any kind of person and not just by individuals diagnosed with the mental illness "OCD".
People affected by this syndrome state, that you are happy when completing a level, but you are happier when it is symmetrical as well and you feel a slight disappointment in yourself when it isn't symmetrical

"You can only feel the true satisfaction of completing a level when everything is symmetrical. When I defeat the last zombie, I will even take the shovel and remove plants so that everything stays symmetric."
