How about not have that attack thing?
OR 2 versions, one for Zombie games where they target ONLY zombies, and one for RPG's (Not just city, because you can just edit the Clothing and Weapons.) where they attack others depending on personality. I personally think this is an AMAZING idea, however i think you should start a pole on if its good or not, and if there should be some Notepad Hao-to-edit file in it.
Great idea but it would probably be like 99999 lines of scripting 
Agreed. Lets go spam Ephialtes, Space guy, or Rotondo with "Script this please!"
Not really. We would jut get banned 8D
