The best feature of PSN is the cross-buying! Being able to sign in on my PSP, PS3, or PS4 and buy things for any platform is great. Even adding the ability to use the store on mobile is also a new, useful feature. Great function that only Sony products can use.
I've been playing AC3, and I'm quite bored. The only thing keeping me going is the story. I played AC 1 and 2, got two hours into Brotherhood and then stopped because I realized how amazingly bored I was. Thought 3 would be different, but it's the same feeling. At least I got it as a gift. I definitely will not be buying any new ACs unless they drastically change the formula.
My personal favorite is in Fat Princess on PS3. When the enemy breaks into your base to steal your princess, the narrator says "they're in our base, killing our dudes!" in his scholarly English accent. I lol'd.
