In terms of management, there's going to be little changing on the ground for Acclaim Games, as previous CEO Howard Marks will continue to run the studio for Playdom. Playdom itself has been purchasing several smaller developers and studios, especially those focusing on Facebook development. No word on whether this will affect management of any of Acclaim's existing games, although it seems unlikely given the circumstances. What is certain is that it's another installment in the distance between social gaming and MMOs being shortened.
