We all know Nintendo have this persona of a family friendly gaming company, but lets not forget that there has also been some very mature content on their systems over the years too. What game or games have you played on a Nintendo system have stood out in terms of mature content or violence. Killer 7 and Madworld are ones that automatically spring to mind for me.

Madworld, Mortal Kombat, Killer 7 etc etc etc

SSBB.

Assassin's Creed IV Black Flag

Mortal Kombat games or MadWorld for me.

RE4

Prob Manhunt 2.

Very interesting question.

Turok 2 was very violent, as was No More Heroes and all of the Resident Evil games. But I think I have to give it to Dead Space Extraction. It's almost non-stop blood, gore, and violence.

No more heroes 1 and 2.

Ive added a poll of some of the popular ones, let me know if any more need adding :)
