Dark Souls is the hardest game I have ever played. Period. Death is part of the game. This game is not for people who like to walk into a place guns blazin. You have to use strategy and learning from mistakes. Despite my failure to complete the game, Dark Souls is an awesome game and I definitely recommend at least trying it.
After spending hours in what I would consider the "tutorial area," I finally get to enter the world that is Dark Souls. It was only then that I understood why this game got so many high marks from so many trusted gaming reviewers. The leveling system is simple yet complex, and the combat is put together very well. The atmosphere is stunning, ranging from claustrophobic dungeons to standing in the middle of what seems like a castle for giants. Even 45+ hours in, I feel like there's so much I haven't even seen yet. And the best part of that is, that I'm right. Just a quick note: this is definitely NOT a game for the average/casual gamer. Those going into it need to know that dying will be something you need to get used to(and fast), and the difficulty level is by far the most unforgiving I've played in a video game to date. But if you are willing to give up some of your sanity to get into this game, I can honestly say you will not be disappointed. Not even close.
