The last review that I had in my "to do" list is 
Fate/complete material III World material., that was released in November and I received quite a while ago.

This is the 3rd book in the 
Fate/complete material set, focused in the settings for the world of 
Fate/stay night.
I tought it would be a forgettable book filled with the kind of information that the fans loves to discuss and made flame wars about it (and actually happened at 
Beast's Lair) but it also includes the new images made for 
Réalta Nua, so it kind of redeems the book for me.
I hate when the followers of a series tries to overanalize every single piece of information and rages when new information emerges contradicting a previously established fan speculation, and 
Fate fans seems really prone to do this... Really, for me is more important to see compiled all the new 
Réalta Nua CG than know if 
Shirou is able to replicate Excalibur or not...
Anyways, moving to the contents:

The first part is an explanation of the Holy Grail mechanics and the summon system.

A complete timeline, before and after the events of 
Fate.

And again each servant bio, this time more centered in their abilities and weapons.

The explanation of how magic works.

A compilation of background scenery and locations from Fuyuki. In the picture, 
Tohsaka's residence 
that I visited in real life.

A 
Nasu Kinoko FAQ answering several questions.
The rest of the book is thankfully all artwork, focused in the additions for Réalta Nua:

The infamous dragon scene that replaced the mana transfer between 
Saber and 
Shirou both in 
Réalta Nua and in the anime.

Newly drawn scene is 
Saber's route.
Rin's summoning scene.

The 
Rider induced dream in 
Rin's route, featuring yuri action between 
Rin and 
Ayako.

The newly drawn character cuts.
The next part is promotional artwork that not appeared in the previous two books:

Dekgeki Playstation magazine cover.

The cover for a Newtype extra booklet called Arts & Words and a 
Saber shikishi.
Rin and 
Archer illustration used in a telephone card.

Since the post lacks of 
Sakura presence, here is her picture for a trading cards collection.
And the last few pages includes the images from the new epilogue:
"Yes... welcome back, Shirou"
