What you will see in your son's game, if this iteration of GTA is anything like its predecessors, is
incredible interactive violence
aimed at police officers (whom you can shoot in the head and see the blood spray), innocent bystanders (whom you can run over with your
car just for the heck of it), and of course the plentiful female prostitutes you can have sex with and then filet with a knife or stomp with your feet in order to get your money back.
