MetaPlace

Metaplace was a software platform intended to democratize the development of Virtual World-s.[1] The platform is developed by Areae (now officially changed to Metaplace Inc.), the company established by Ultima Online and Star Wars Galaxies designer Raph Koster. According to the official website, the platform is "client-agnostic", which means that virtual worlds developed on Metaplace can be accessed using any device that connects to the Web.

In January 2010, the company pivoted towards using its virtual worlds platform to build Social Game-s on FaceBook. It released two successful games on facebook using its platform, Island Life and My Vineyard after which the company was acquired by Play Dom.
