...in a video game.
"prostitutes are super hard to kill"
Kids should not be playing games like this. At all. It's the equivalent of giving a kid an R rated movie. But most people still equate ALL video games with kids. KIDS SHOULD NOT PLAY THESE GAMES. In fact I don't know who the hell WOULD play a game like this.
I know of very few games were you can do what this little kid is describing.
And in those few games it's generally NOT a good idea to go around killing everything.
It must have been one of the newer GTA games which I have not played.
