This game differs from traditional western RPG's clear that it has no stringent main story or side quests with lots of NPCs, the storytelling is very minimalist (if one can even speak of storytelling), since Dark Souls will not tell a story. It lives off its mystical, beautiful and at the same time threatening world, the incredibly demanding and rewarding fighting Boss Fights.
To combat system: The combat system best in my opinion, which I so far been able to experience in a role play. There are a plethora of different weapons and spells that change the combat experience clearly and invite to try out, including up Bethesda should cut a slice at the next Elder Scrolls. Initially, it will probably seem a little overwhelming and difficult, but in reality, the battle system takes very closely, ie it requires the player to approach with brains and punishes mistakes often with death. On the other hand, you can play through the game with a Level 1 character, provided it is so good, and that's what makes the battles much fun.
The world looks like from a Castlevania game: a huge castle, a wealth of different enemies, some huge bosses and picturesque scenery. Many places will be without thorough exploration or the help of Internet Guides Never, since the game does not participate in the hand a Discover, and that's exactly what a so captures and inviting you to explore. Such attention to detail I have long not seen.
Criticisms, there are in my view only two: once the constant framerate dips in Blighttown and playing together with friends, where you have hope in the best trial an error manner, on the same server to land as the friend, so you get to see the summoning characters , However, these pale in terms of what makes Dark Souls so good and so right.
Therefore, a strong buy recommendation from me, because this game is a love letter to the sophisticated (RPG) gamer!
