In my humble opinion I suggest this is a game worthy of your money. I highly recommend this game if you are into a stealth game or if you like to use brute tactics and force in order to achieve your goal.

Introduction:
The game introduces you as the "Royal Protector" Corvo Attano, which is returning back to Dunwall to meet with Jessamine Kaldwin; the empress of Gristol, to tell her that he has not succeeded in finding a solution to the rat plague currently infesting Dunwall. His reunion with Jessamine is made short however, since she is assasinated right infront of him. Corvo tries to battle the assasins, he is however knocked out, giving the assasins an oppertunity of escaping. Shortly after "the royal spymaster" shows up blaming Corvo for the murder of the empress. You then have to find out who murdered the empress, and reclaim your honor.

Gameplay:
This game offers diversity in terms of strategy. I personally found myself discovering new ways of infiltrating target objectives on my third and fourth playthrough. This game also allows you to choose how you want to play. You can choose if you want to kill someone, or if you want to complete the entire game without killing anyone. The way you play the game also affects how the ending will turn out. You are also able to use certain powers, some of these powers can be used for a stealthy approach, some can be used to kill.

This game has some glitches and bugs which I find a bit frustrating. Dialogue between NPC is cut whenever you are being detected by them. The dialogue does not countinue from where it stopped once they return back to their un-alerted state. There are also situations where something you haven not done is count as a kill, which is frustrating if you are trying to achieve a playthrough without killing anyone. It is also hard to recognize some of the NPCs' who will be alerted by your presence, and those who will not.

To conclude this short review: I believe this game is a good investment, since it offers great diversity in playstyle and player based choices. The story is also very good. The things I found negative about the game are minor. As a side note I want to mention that I have not experienced any major problems with this game (only very few crashes, as expected).
