Traditional cRPG and JRPG are worlds apart. One tries to emulate the tabletop experience, while the other is more of a power trip with no decision making or character creation/development whatsoever.
First, I want to say that I prefer western RPGs over J-RPGs.
It used to be the other way around, but the western RPGs have evolved a lot, become better and more immersive than J-RPGs could be.
That being said, I find the current generation of JRPGs especially weak compared to the great games in that genre that came out earlier.
BUT if there is one thing that JRPGs do well it has to be the emphasis on characters and story.
In Star Ocean for example you are confronted with a lot of choice and consequence - if you let one character join you, another might not want to
and the group takes an entirely different path, resulting in different scenes/dialogs throughout the game and at the end of the game.
Especially Star Ocean 2 is a really great and underrated JRPG.
The idea of crashing on an underdeveloped planet and having everyone think that you are the hero of light
just because you have a gun that shoots lasers is fantastic.
The first choice, the choice of character at the beginning already can turn everything into a whole different game,
because you follow the story from different perspectives, of one of the two characters that work together.
Uhm... that's enough.
I just wanted to explain that most J-RPGs out today are the sorry leftover of a glorious genre of games.
Buuuut that's a whole other story, let's talk about DA:I again.
