The success of Minecraft can be boiled down to the fact that its near-infinite replay value and gameplay mechanics mean players can unlock limitless creativity. While some may think of it as a video game more suited for kids, its appeal goes beyond age barriers, with many adults enjoying Mojang's open-world sandbox title. It can also be a peaceful experience as well, and while it does have some violence, it's not what many would consider extreme. That is, until these people came along.
