Not really sure if this will come. or something along these lines. but gee it would be fun. for people committing the crimes and the police attempting to catch them
the idea is the ability to place a note with a message on the body of the guy/girl you've just killed/mugged or even the ability to place a note at a location
A note containing a quote, a message or even a well written riddle to either keep the cops on the trail or throw them off.
now i'm sure anyone could just load into a game. go and rob some people or even go on a murder spree. But seriously. if your going on a murder spree you are probably going to get caught.
Even killing one person per week. stalk your prey. leave notes as clues in town square. or even inside of a police station to let them know you have you eyes set on someone else. either it be a politician who's morals you don't fully agree with, someone who said something in town square that rubbed you the wrong way.. or even a taxi driver who took you to the wrong place.
