Second Life

At Oculus Connect 6, Facebook announced a new social VR platform called Facebook Horizon. It won't launch in beta until 2020, but will let users build their own avatar, explore worlds, play games, and even create their own environments using the built-in creator tools. Sound familiar? It's Second Life all over again.

Xbox Live, World of Warcraft, and Second Life have all been targeted by counterterrorism groups in the United States and United Kingdom.
