Now to limit what others see of your online game playing:

2) Under Apps and Websites click on Edit Settings
3) Click EVERY app in your list. Remove any permissions you dont want that app to have
4) Under App Privacy click the drop down and click Custom.
5) Under Make this visible to select "Only Me"

Now no one other then yourselves will see what games your playing.
