Pokemon Shuffle is the one and only reason. Annnnd unfortunately I'm addicted to it
From what I can tell with Pokemon Shuffle is the game updates itself, doesn't do the updating we are accustom to. Why I say this (and of course I can be wrong) is because 2 days ago it was on version 1.1.4 and today I noticed it was on 1.1.5. I did not update it, no one else touches my 3DS. Also I have no problem checking in since the new firmware went out and I'm of course, only 9.5.
So i think Pokemon Shuffle will survive this.
