My brother has a PS4 with lots of digital games. He activated his console as primary because my niece also plays those games. So my console is secondary.
If I download those games from his account I wouldn't be able to play.
My idea is to download games from his account on a secondary console (my console) and play them using the same account, i.e. my brother's account.
Will this affect his game data? I have seen it starts fresh games on my console. If it synchronizes will it spoil both our data?
