Alternate names: Thieving NPCs
Name variations: thieves
The first video game about Stealing NPCs was released on November 21, 1991.
This can range from actual thieves to animals to "malfunctioning" robots to gnomes to ants.
Usually but unfortunately not always the player gets the stolen items back after showing the thieves the error of their ways.
This is named stealing npcs to avoid people not familiar with tags tagging cases of regular outlaws with this (or characters only named thieves).
