My brother plans to get a PlayStation 3, and I get to play on it. That means I'll finally (!) be able to play the Ratchet & Clank Future series.
In the wake of the recent attack on PSN, I'm now rather cautious about getting a PS3, more so than I want to be. But in any case, what do I need to know or be wary about regarding PSN, specifically for the new Ratchet games? Even basic questions like "do I need an account for these games in the first place?" would be good for an answer, because I can't really find much info addressing that. I'm equally interested in what I'd be missing out on if I stay offline, though.
I know that demos are available on PSN, but since I'll be buying the games anyway I probably don't need them. I'll also be going to the store and buy the games from there, instead of purchasing online.
