Playdom has been on a bit of an acquisition spree the last few months. After acquiring Acclaim Games back in May, the company recently announced that they have also acquired Metaplace, the virtual world platform developer co-founded by industry veteran Raph Koster and John Donham that shut down back in January. Donham and Koster will stay on with Playdom in their new respective roles.

With the acquisition, Metaplace's CEO John Donham will head Playdom's new San Diego office, while Koster continues his creative design work with Playdom's co-founder and chief product officer Dan Yue. Metaplace's Business Operations VP Jason Hable will move to Playdom's Mountain View office to oversee the company's monetization efforts.
