Here's how to turn OFF telling everyone you're playing a game: Under ACCOUNT, select PRIVACY, then 'Edit Settings for Applications and Websites' - lower left. Down at 'Games and Applications', set it to 'ONLY ME'. That will stop spamming everyone's feed with news that you're now playing whatever-the-hell. You can also turn off that 'Now Friends With' alert, etc., if you want to. (copied from Amie Gantt Spengler), Works for Facebook.
