Quick, how many friends do you have on facebook? If it's in the triple digits you've probably missed the point. I rememeber when I first started using Facebook in middle school. Back then, I thought that the way this site was supposed to work was that you added every one of your friends and acquaintances. Ah how stupid I was.
Last Christmas I finally got my hands on a copy of From Software's Demon's Souls. After all of the hype I've heard about the difficulty, I can say that I'm not at all disappointed. One of the game's signature features is its unique multiplayer experience. Players can be summoned into others' games to assist or they can invade someone else's game to kill them. Players communicate through messages left on the floor to either help or trick a player ("Use luring attacks on the next enemy", "It's safe here").
