Ok really... WHY?!?

Ok, why do you have to sign in to play. I just wanted to play a cool, popular game, but nooooo you have to sign in. All I wanted was to play with my friend(OPDude444),(Mystic type). Why cant you just play and save it on your game storage. I mean seriously. I am a 12 year old, and I have better ideas than these producers. Really.?
