Dark Souls may be one of the most Aesthetically beautiful games I have ever seen. There is not a single enviroment in that game I would even rate as low as above average.

I dig for examples in a game like Skryim to find a great looking enviroment or area (The only three being the underground Snow Forest, the Underdark area, and Markarth) and yet none of those compares with any of the areas of Dark Souls.
