New Crisis Core chapter (Chapter 3) added a lot of cool things.
Was nice to see Zack interact with Scarlet—I always felt like the Scarlet/Heidegger/Palmer side of Shinra and the SOLDIER side of Shinra were too segregated until now. For a long time, the only interaction we had between them was Palmer's reaction upon seeing Sephiroth in Shinra Tower. At a character-specific level, it was just nice to see Zack and Scarlet talk for the first time since they have very contrasting personalities.
Zack helping a 3rd Class SOLDIER quell a monster attack was very cool, almost taking him under his wing the way Angeal did for him. Then, Zack saying "I'll be Angeal for the day" when helping a scientist with his research was very cool too.
The scene of Zack meeting with the Turks was streamlined, but nothing important was lost, which is good. I like that the artist actually slightly changed Reno and Rude's portraits (gave Reno short hair, made Rude clean-shaved) to fit with Crisis Core being a prequel. Honestly, I fully expected the portraits to be the same, and would've been okay with it, but I'm pleasantly surprised to see the attention to detail.
I'm happy that the entire cinematic of Genesis and Angeal sparring with Sephiroth was included. Always extremely cool to watch.
I did not at all expect to see Ever Crisis create a brand-new Angeal Copy. To stop Zack from catching him, Hollander summons a new character, A-Rejector, to act as the boss of the chapter. Honestly, I expected the boss to be Angeal himself, but I'm glad it wasn't, since the whole point of the scene was that although Angeal was attacking, Zack refused to defend himself. Very happy to see a new Crisis Core boss was created instead.
