Basically because I enjoyed playing with friends that had the game as well for Demon's Souls. How it's set up is that for Dark Souls, it's separate smaller servers, instead of one large server like with Demon's Souls. Even though it did take me over 150 hours to platinum the first game, I had others to experience it with. When you have no one to really play with in the 2nd game, it makes the game feel a little more like a grind. Not that it's hard, just better with others.
