I'm a little puzzled about something on my PS3 I have a PS+ account and my girlfriend has a account thats not signed up to the PS network she created it because I downloaded Little Big Planet 2 as it was free for PS+, if I sign her up to the PSN can she still play little big planet 2 on legal terms for example is it classed as account sharing.
It's legal, yes. Even if it wasn't, thousands do it, that's why they knocked it down to 2 PS3s able to gameshare.
As long as the psn account with those games are on the playstation then yeah. But just like Aaron pointed out.
