The collector box is remarkable, there is nothing to complain about. It is a high quality and a very good finish as well as the artbook it contains. This is very beautiful, slightly missing text for my taste but is enriched by the application of augmented reality associated with it (free download).
The CD of the Soundtrack is also very good. The music is interesting but I find them in the mood shifted with the game for some (then you find yourself in combat with soft background music in the background ...).
The mouse pad is not of exceptional quality but has the merit of being beautiful.
The DVD / Blu-Ray behind the scenes contains interesting content.
Nevertheless, this extension is honestly not essential. This is a course but not fantastic. The collector's edition is for me a great success and a decorative element in itself.
However, prices at the exit of this extension were quite high extension 40 and 80 for the collector's edition, I do not see why there are 10 additional cost compared to a conventional extension.
In conclusion, I enjoyed this but I doubt it meets fully all its buyers with regard to the content game. Besides when you only interested in attributes "collector", great .
