I just want to say before I start properly that I LOVE this game, it has drained hours out of my life and there have been times of frustration but nothing can compare to the elation of defeating a boss that has robbed you of multiple souls and humanity.
The prepare to die version shows people how DLC should be made, it fits seamlessly into the dark souls game as if it had been there all along. As other reviews state, this game is hard, but not I don't think too hard. It is a game that doesn't hold your hand and doesn't tell you what you need to do. It is up-to you to use your brain and there arent many games out there that do this nowadays.
I have not played a game since Monkey Island that has had me talking about it as much with my friends in the pub, sharing tips of how to get passed a point that has had me stuck. Granted its not exactly the same ( no using a fish to bait a bird in order to obtain a collectible) however the premise is the same. You need to explore and you need to use your brain in order to progress. If you are the sort of person that needs an arrow pointing you to the next checkpoint, and a glowing arrow over the person you need to speak to then look at one of the other many games that are out there because this isn't for you. However if you are willing to invest time, to ignore your children and your partner, and to fall into a bi-polar spin of depression, frustration and manic elation running around the room and cheering when you have managed to defeat that boss, then this wonderfully made game is just for you.
