Just logged in today with one of my alt accounts and it is no longer locked to the account that originally purchased it. This ticked me off so much when I originally bought it from the PlayStation Store that I never bought a PSN version of any game due to not wanting to get burnt again by Sony.
Why would I buy a game if my whole family can't play it on there own accounts? I'm sure the original account must be present on the console your playing on but I can't confirm this because my wife is playing on her account at the moment. lol
Well thumbs up to Sony for finally getting rid of this stupid restriction.
