Dishonored

This upcoming game is being developed by Bethesda, so you know it will involve gratuitous amounts of open ended objectives. Actually, that is one of the main concepts the developers push in their marketing strategy. Opened ended.

This begs the question, will it be as open as Skyrim? Don't get me wrong Skyrim is OPEN, but not as open as they would make people believe. When I first heard there would be a "radiant storyline" I thought it would be NPC's giving you quests every so often, like solving disputes or raiding certain dungeons or caves for certain items. But what they really had was a mediocre "radiant" storyline and a one quest per important NPC kind of thing going on. Hopefully modders will make Skyrim insanely more immersive and give it what it truly deserves, a life of its own.

Back to Dishonored, although it's still in development the developers have said that they intend to the plot about a former bodyguard to the queen being framed for her murder, and subsequently hunted down. You fill the shoes of this man and you decide to exact revenge on those framing you. The game itself revolves around how much blood you want to spill to get something done and what's cool is that the atmosphere of the world changes on how much blood you spill.

Let's say you are trying to infiltrate a building of a man you think is associated with the plot to frame you. You have options of sneaking by, only killing guards when necessary, or just going gung-ho and massacring the whole lot of them. This might affect how people view you or how alert future guards might be, or so they say. Again, the game is still in development and no actual gameplay footage has been released, so I can only presume this is what they are trying to accomplish.
