I got the special edition and I liked a lot the art book it includes, it has a lot of stuff and illustrations, on the other hand, the music CD could include more songs, but the music is amazing, I like more the soundtrack of xenoblade chronicles for wii.
The game has a very good story, the worlds are huge and some enemies are very challenging, the battle mechanics are complex at the beginning but with some practice and battles you start to master the gameplay, there are a lot of stores, I still dont know how to use some of the things that you can find in the game and in the stores. I am loving the experience, its a rich experience and I still have a lot to explore and to know.
