Last Order a été décanonisé.

Though once counted as part of the Compilation on pg. 25 of the FFVII 10th Anniversary Ultimania (pp. 23 and 25 of the Revised Edition) in its “Final Fantasy VII series” section, Last Order and Dirge of Cerberus Lost Episode were later identified as “works outside the Compilation” (コンピレーション外の作品) on pg. 226 of the FF 20th Anniversary Ultimania File 1: Character guide.

As such, these two titles are no longer considered canon to the FFVII series.

De toute façon, même à l'époque du dév' de FFVII:CC, ce court métrage n'a pas été pris en compte suite à la mauvaise réception critique des fans:

"In between Advent Children and Crisis Core, there was a short animated feature called Last Order," explains Imaizumi. Last Order, like Crisis Core, was also about Zack and how he related to the crucial events at Nibelheim that were depicted in the original Final Fantasy VII. "When we made that feature, we changed the presentation of that event from the original Final Fantasy VII. And the fan response was - well, there was considerable negative feedback in regard to changing a part of the story that they considered integral to the whole lore. So we listened to that and learned from that. And in fact the Nibelheim incident is presented again in Crisis Core, and we were careful not to make the same decisions that we did in Last Order."

De toute façon, même à l'époque du dév' de FFVII:CC, ce court métrage n'a pas été pris en compte suite à la mauvaise réception critique des fans:

Tu m'étonnes. Avec toutes les incohérences qu'il y a dans ce court métrage:
-Cloud qui revoit Tifa (ce qui fait que tout le background de Cloud n'a plus aucun sens dans le jeux)
-Sephirot qui se jette lui même dans le vide

Donc les canon: BC CC FF7 OWTS AC DOG.
