This shouldn"t come as a surprise to anyone: when compared to the Xbox 360 version the difference is so severe that it looks like a different game in some shots. Jaggies aside, there are a lot of visual problems such as absence in depth of field shadows, realistic lighting, and volumetric fog — all things that do attribute to immersive gameplay.
The comparison between the two show that the Wii"s graphics are definitely better than the original Xbox, but are they sufficient for visual junkies?
