How good is Phantom Trigger

[Akshay]

I just finished all of the main Grisaia Trilogy, including all the short stories. And today I came across the Grisaia:phantom trigger series, which happens in the aftermath of Rakuen, with a new cast of characters. 

To people who have played this, how does it compare to the original trilogy, or even the first game in terms of both plot and characters?

it is better

It uses the same world and the organizations built from the ruins of the ones Yuuji worked for, but it is significantly more focused on the assassination/spy issues.  The school Yuuji and the others used to attend has become a training camp for agents, and the main characters are the best of those, kids who are actually already being sent out on missions.  There is a lot of killing in these games and a lot of the stuff with the organization that was mostly glossed over in the original trilogy is laid out rather bluntly.

Whats the average length of the volumes?

Is the story structured around one girl per volume, or is it all encompassing and substantially connected? 

Are the references to the previous series frequent, or is this cast of characters and the story completely detached from the original?

thanks.

I read through each of them in an hour and a half to two hours... I imagine that most people would manage to do so in three.  The series is episodic, not heroine/romance-focused.  Each volume covers an incident, mission, or episode in the characters' lives, at least so far.

I've enjoyed them greatly, they're not too long like Clephas pointed out.
