This "new permissions" set is at least far more detailed than the FarmVille request, which left many users wondering exactly what they were giving Zynga access to. Here, we're told straight up that by giving Zynga these additional permissions, you're simply allowing it to share your gameplay activity in the ticker (including achievements you've earned or goals you may have completed while playing) with your friends. Facebook apparently requires it to do so, so here we are.
You'll be able to give Zynga permission (or deny it) when you see a window like the one at right appear in your screen. From there, you can either hit "Allow" to let yourself appear in the ticker, or "Don't Allow" to keep yourself hidden. Your own gameplay experience won't change, and nothing in the game itself will change either. This all goes back to how much information you want to share with friends about your gameplay activity, all in the Facebook ticker. That being the case, feel free to choose whichever option you wish without the fear of penalty.
Will you allow Zynga to share your gameplay activity with your CityVille friends? What do you think of the Facebook ticker as a whole? Sound off in the comments.
