Rovio has been valued at several billion dollars, while Zynga is somewhere around $13.8 billion. This has made Activision, who hasn’t been very active in the social gaming arena, reluctant to jump in.

“Valuations of some of the companies in that space are out of whack, so that’s an issue when it comes to acquisitions” said Activision Publishing CEO Eric Hirshberg, who added about social games, “We haven’t made any formal announcements, but don’t mistake careful, methodical planning for inaction. Any new place where people are playing games, at scale, is something that we’re interested in.”
