For young fans of Fallout, Assassin's Creed and Splinter Cell there are elements to this game that might be enjoyable. It is linear, predictable and very easy. The 6 is because although it does a good job doing what it does, it offers nothing special and nothing of interest for those who like surprises and challenges. If you simply want to pass some time, a good choice. For quality time, look elsewhere.
The story of Dishonered is something you can read on your own. Basically, you got screwed over and its time to kick some butt and get your revenge. You go through missions choosing how you want to do things. Do you want to walk through the front door and shoot every one? Or would you rather find another way inside and keep quiet.... Would you want to kill your target in front of people? Or do you want to lead them elsewhere? ....
The game is really fun in terms of freedom (this is not an open world game, mission wise it is not linear). You also have special powers, that's right. And as you collect these things called "runes", you can get even MORE cooler special powers. Like controlling people, or summoning a group of rats to eat people alive (FREAKIN' AWESOME). However, just like anything Dishonered has its negatives. For example, the story line just isn't that intense. You will find yourself skipping through dialogue because you just don't care. And there are certain things in the game that make you say "Oh.. well that doesn't seem right" for example you have a freaking heart that you carry around with you to find runes. Who the heck came up with that idea?
All in all, its a game that reaches new heights and really will grasp you... UNTIL you put it down for a couple of days. I was out of power from hurricane sandy and didn't get to play, but when I put the game back in a couple of days later - I found it super difficult to even get back into the game. It JUST doesn't grip the player for long. But if you put aside that and the sillyness in some aspects, you're going to have one EPIC adventure.
