I used to have two accounts on my PS3, one in the UK and another in the USA.
I used each one of them to download Exclusive Content which was unavailable in each region. Sometimes I would buy games from USA, sometimes from UK. In PS3, it wasn't a problem. I can play both of them without any problem. Is this possible in PS4 too?
So let's say I activate two of my accounts in my PS4 and set both of them as primary account (I think it's possible). Can I play all of my games in UK account? For example if I buy a hard copy of Assassin's Creed Black Flag from USA, can I play it with my UK account?
