After a long wait for the release of Chaos;Head Noah, I began to read the entire SciAdv series in release order (Except Steins;Gate, I read it 6 years ago).

Now I completed Chaos;Head Noah and Robotics;Notes Elite. And despite all the wild stuff that happens in Chaos;Head, I almost didn't feel sad and depressed (I treasure this feelings most in VNs). Chaos;Head Noah was a bit not about that, and more like madness, bloodshed, psychotic. For me, personally, this is good, but not awesome. I don't even want to write a review for Chaos;Head Noah.
Robotics;Notes is another matter. Yes, indeed, there is everyday life and some people wrote that the game is calm. To such people I want to say - What are you talking about? There is tension and mystic, although not to such a crazy intensity as in Chaos Head. There is sadness and drama. I even had goosebumps.
Also, people write that it's a slow ride, but I've always been interested in reading. The desire to continue reading was bigger than in Chaos;Head. Plot twists are also presented (Though ending was predictable after end of 11th chapter).
I really like the main character. He has never annoyed me, on the contrary, I share his opinions. But Akiho was a little annoying.

And of course, it is impossible not to say about the 3D format: It was very unusual, sprites are constantly moving. By the end of the game, I fell in love with this style.

Great soundtrack. I often was stuck on main menu to listen to this beautiful melody.

I glad that I waited long 2.5 years for english release of Chaos;Head Noah. References and characters of previous games are worth it.

Also, Nae-sama, yes, Nae-sama! After Steins;Gate I never expected to like her so much, but there we go. I love her now.

This vn is not about them. Heck, this vn is not even about Phantom trigger cast. This vn is about new third cast - class D of Mihama and some other employers of SORD. A lot of them had awful childhood and we need to help them overcome it. Typical usual Grisaia. Especially Ena's story was impactful, brutal and really had Grisaia vibe.

So I can understand some people's disappointment because of rare appearance of original cast. But not me. I like Phantom Trigger and I like Chronos Rebellion too. These vns not on level of original trilogy, but still good for me. More I read - more I was hooked. Moreover original cast gets some action in later part of the game. But what a irony - some scenes with girls from original trilogy was most boring of all.
Nevethless, I've always really liked the idea of having characters from all games of the series met together and I got it. (Now my dream is to have new SciAdv game in which all protagonists of the series met together and working against commitet).

Somewhere I seen that Cronos Rebellion is finale of Grisaia, but ending doesn't seem like it. I guees we will see more Grisaia in future. I definitely waiting for it.
