In a virtual world I can do things I cant do in real life. If I want to spontaneously jump off a cliff, In a virtual world I can. If I want to start a gang, In a virtual world, I can. I can potentially live a live that is more full than a life that anybody has ever really lived. There are no laws of physics. There are no real life changing repercussions for choices made, only repercussions within the virtual world.
