Gamespot has their review out. They gave the pc version 9.5, ps3 9 and xbox 360 8.5. Apparently graphics on ps3 is quite a bit better than xbox 360. They say gfx looks best when viewed from the BG camera angle and that's why it looks much better on pc. Overall they love the story and gameplay elements on all version.
