Second Life

Second Life is a free 3D virtual world and metaverse where users create avatars, build and own virtual property, conduct business, attend events, and socialize with others globally using voice and text chat. The official client is the Second Life Viewer, a full-featured application that serves millions of residents who treat the world as a persistent social, creative, and economic platform. Users range from casual explorers and socializers to content creators, entrepreneurs, and educators who conduct classes and host conferences in-world. The app is cross-platform and free to join, though cosmetic upgrades and virtual property ownership require spending (Linden Dollars).
