Just imagine if some kid had brought the game to school without opening it just for bragging rights, opens it in school and some teacher or other adult sees the baggy.
The kid would automatically get sent to the principal's office to await the police, after which he would be expelled and branded a drug dealer because of having an illegal substance within a school zone (namely the school itself) and possibly even face jail time.
In the mean time, the parents would be hard pressed to fight it all because it was already present in the game case when purchased.
Talk about a nightmare scenario! :O
