I despise it. I signed up to it years ago...and now am bombarded with greeting messages each and every time I open Game apps. I've no interest in it, I don't want to use it.
There does not seem to be a practical way of disabling it. If I sign out of the app through settings, it seems to cause issues with iCloud (particularly noticeable with the Apple Watch which prompts me, after a while, that my "iCloud password is wrong". So then I sign into iCloud through settings on my iPhone and, presto, awful Game Centre is activated again. What is the point of having separate settings for Game Centre if it's intrinsically linked to iCloud?
Grrr.
