 Many traditional gameplay genres naturally lack violence and application of the term "non-violent video games" to titles that fall under these categories raises no questions regarding accuracy.For game developers and designers who self-identify as non-violent video game makers, however, the challenge has been to expand the concepts of non-violence into such traditionally violent gameplay genres as action games, role-playing games, strategy games, and the first-person shooter.Emergent and more recent gameplay genres such as music video games are for the most part naturally non-violent.
