An amazing game as we all know, with few issues, that I actually prefer to the 360 and PC version.
As I'm reviewing the PS3 version, I'd like to explain why I feel this version is best. I've had minor luck at best getting the PC version to work fully. On the average computer, you can't regularily experience the amazing graphics fully. Each mod you download means more chances for the already large amount of bugs on the PC. The 360 version isn't much better, and I find loading times are the same as on my PC, and it gets laggy during battle, when moving around the wilderness, or when viewing huge, beautiful scenes. The colors are also highly saturated to a degree that burns the eyes, with everything from faces to walls to small objects glowing bright colors. Some may like the look, but I hate it. It ruins immersion, is just silly, and is ugly--looking through the Guide book shows this well, as often dull colors, the "shadows", contrast against shining colors.
The PS3 version, while lacking the ability to modify it or get achievements, is really in my opinion better. Not only is the disk hard enough so that slinging it at unsuspecting passersby may cause brain damage, but the graphics are far more realistic and run beautifully on a 1080i HDMI TV. They're realistic, and you can actually see the textures. I've had almost no lag whatsoever, loading times are shorter, and it doesn't have the game breaking bug that the PC and 360 version have with Shivering Isles.
All in all, the game is wonderful whatever you play it on, but for those who don't care about modding or achievements and just want to play an amazing game, I suggest the PS3 version.
