Metaplace has developed an in-browser virtual-world engine which can be applied to social games. Founders Raph Koster and John Donham previously worked at Sony Online Entertainment, where they helped develop games like Star Wars Galaxies and Everquest II. At Metaplace, they’ve already launched two Facebook games: Island Life (with 457,000 monthly active users) and My Vineyard (with 822,000 monthly active users). A third game is on the way. Playdom will use the virtual world game engine Metaplace has developed to create even more games in that genre and add the game design studio to its growing roster.
The company has raised $9.4 million from Charles River Ventures, Crescendo Ventures, Marc Andreessen and Ben Horowitz. The acquisition price is not being disclosed.
Playdom just raised $33 million of its own last month from Disney’s Steamboat Ventures and Bessemer. Some of its other recent acquisitions include MMORPG developer Acclaim Games, Facebook game developer Offbeat Creations, Three Melons, and Merscom.
