You can tell that with each route they have been trying to elevate themselves and mostly succeeding. In each subsequent route they add more girls, more scenes with more variations to the dialogue, and it just comes across as more ambitious even if not completely polished. In a way it's a shame as an Azula fan that the fire nation came so early in their evolution. So far B4L is turning out to be the best chapter yet even though the memory game is super annoying.
Yes you can clearly see the pattern of them wanting to surpass themselves with every next "book" they make.
Although for my taste I don't see book 4 love route as the best one so far.
My book rank would go something like this:
Book 1 love route<book 1 slave route<book 4 slave route<book 4 love route<book 3 love route<book 2 slave route<book 3 slave route<book 2 love route
However, I'm not subjective with this ranking nor do I try to be since I'm biased towards certain characters.
In short, love Azula, dislike/hate Korra (depends on her "version"), don't particularly care about Toph, can enjoy Katara being an obedient slut.
Also I think it's too soon to really judge book 4 love route.
Depending on the characters they add and the execution, book 4 love route may move up in my rank although looking at how good book 3 slave route is and especially which characters are involved in it... ngl it's going to be hard to beat.
kind of agree with both, except for the rating of books/routes (matter of taste/prefs)..
book 1 the idea was there and you can still see the "how to we get there"
book 2 they then knew what to do and where to try, the improvements visible
then book3 i really don't know.. is it better, or not, than book 2, couldn't tell. matter of prefs again, some root for this girl some for that one. the quality is solid about the same.
now book 4, i think that's where cBob started to really get strained by WhateverItWasOrIsWeStillDontKnow combined with the beginning difficulties to put a story together. personally, i think he has a harder time to think up a love story, than a slave one.
to think up a love story when you're depressed, i mean clinical depression, might be even harder.
everyone and everything around you is shit, your own self included.. now tell something nice and beautiful. gudluck.
