Multiverse

The Multiverse Network, Inc. was an American startup company creating a network and platform for Massively Multiplayer Online Games (MMOGs) and 3D virtual worlds. Multiverse's stated aim was to lower the barrier of entry for development teams by providing a low-cost software platform for online game and virtual world development. Multiverse provided technology known as MMOG middleware (Multiverse used the term platform). It included the client software Multiverse World Browser (for Microsoft Windows only), a server suite, development tools, sample assets, documentation, and a developer community. The goal was to provide consumers/users with a single client program that let them visit all of the virtual worlds built on the Multiverse Platform. From the consumer point of view, this enabled a de facto network of virtual worlds. Source
