Here are my opinions about Book Five. (SPOILER WARNINGS, OBVIOUSLY)
Zoe's beginning in the hospital was a good way to start an episode. Just the touch of creepy.
Hami joined the rebels a bit too quickly. I can understand getting to brass tacks, but I don't think enough time was spent discussing the whys. His backstory with "magic as a part of him" I just didn't understand.
Ooh boy, lighting Onor Hileriss on fire was hilarious. If there's one thing I can say about this game, it knew how to deal with a villain I loved to hate.
Maybe the wine-seller should have sounded drunker. I'd have believed the quest a lot more if that was the case.
Kian's dialogue with Crow in the boat was awful. I felt like it was the devs trying to bash me over the head with "ZOMG Kian is gay!"
When did Klacks get the soulstone from Westhouse? I know it was after he got free from the calculator. I had to think about it to realize that was probably the reason the Azadi arrested him, but I don't think I should be doing stuff like that.
I loved Saga's design. She looked cool.
I did not see Mother Utana's betrayal. At all. Kudos, that was a fantastic twist.
Crow's death made me really sad. It was shocking.
The end part with Ferdows and shutting down the Engine felt way too rushed. It was an important part of the story that suddenly got regulated to sideshow.
I did feel some sympathy for Brian Westhouse. In the end, I think he went insane due to not being able to go back home, and the Undreaming did the rest. Still, I didn't feel bad about beating him. Mostly because he killed Crow.
Gabriel turned into one of my favs after he stood up to Helena.
I still don't exactly know what the Undreaming was. It was the counterpart to Lux, but I don't get what the undream was? How was he different from the Baba Yaga? I thought it didn't make a lot of sense, and I liked the Baba Yaga's motivation and her philosophy.
Zoe's backstory was tragic and sad, and it made me love Gabriel more. I only wish I'd gotten more hints earlier.
Sahya's death made me laugh. Vamon's even moreso. I didn't really care for Anna, but I was okay with her getting the first stab.
What exactly happened to Mother Utana? We know Kian became the Bloodless King, but did he kill her? I wish it could've been made explicit. I did like his epilogue though. I had him with Saga and Na'ane.
All in all, I'd say I had a mixed bag of feelings, but I think it was a pretty good game. A bit muddied in it's plot, but fun to play and the backstories of the main characters were really interesting.
