The thing is, the game servers are just fine. If we didn't have to go through the Playstation Network we'd be playing the games right now. In fact, some of us were playing this morning after the attack occurred. But since we were already logged in we could keep playing. After the game servers went down for daily maintenance, and we then tried to log back in, did we realize there was a problem.
This then brings up the big question: Why do Playstation users have to first get recognized by the PSN?
It has been asked many times over the years with no good answer. When something like this occurs, why not just let us bypass the PSN and play the games. Yes, we won't be able to add money to our accounts, redeem codes, or buy updates. But so what. We'd still be able to play.
