Well I think that's almost it. The best course of action for sony would be to release a second key for new games, and just let the old games die. What's lost is lost, and there's no feasible way to recover from this. Just save what you can.
Only thing drive me crazy is all these new horror games nowadays is its so dark, all time. I can't even play them. I understand they trying to create spooky but be creative a little, not just darkness with pop out scare scenes.
