When it comes to video games and violence, the two go hand in hand. Frankly, some of the best video games out there, both adult-oriented and family friendly, have an element of violence. Think about it; even Mario goes around stomping on animals and punching bricks. For a while there, those violent elements were enough for developers.
Then they started to add in blood and gore. With games like Doom and Mortal Kombat, shit got really bloody and definitely NSFW.
These are the games that’ll require a long shower and a deep scrub after you’re done playing.
