Ok I see. Although it kinda sucks now they should've put up to 3 activations, you and 2 friends would be fine.
You aren't supposed to share it with friends, So why should they make it 3? You can deactivate all of your systems every 6 months on the website or when you want on the console. Your acting like they are in the wrong for not letting you give away their games for free to people who haven't paid.
Normally I don't agree with activation limits because you end up losing activations but Sony does it the right way imo. It's fine with consoles imo because it's not like we upgrade them every 5 months. So it shouldn't be a problem.
It's not like when you go to the store and buy the same game, Do you get 5 discs for you and all your friends to play at the same time?
