"So according to Sony, you don't have friends, family, roommates or visitors who may want to play the game. Thanks Sony!"
Firstly this isn't true.
You can make a new profile, which takes 30 seconds, log on ,then you have your own game saves.
I have 3 users on my PS3 (It's like a PC you log onto your own profile) and then everything saved there, is your own.
