I don't have a ton of RPG games on my belt, so I'd say YMMV depending on your experience with it. This game is polarizing for some reason. Prior to playing this game, I wasn't a big fan of turn based outside Pokemon. Then xenoblade 2 action auto RPG came and I was spoiled (this was 2 years ago) and was adamant on not playing turn based RPG games. A coworker got me this game though two Christmases ago, and have it a shot last summer, and beat it in the fall and really enjoyed it.
The stories themselves are not super deep. But the art style, music and gameplay are superb. The biggest criticisms from people are that the characters don't interact with each other that much in each other's storylines, and that's actually true for the most part. Other than that, critics think it's repetitive.
I really love this game's gameplay though. the break mechanic is awesome, as well as each characters skills and being able to unlock different jobs (as well as secret ones). Story wise it's alright. Characters in the story are interesting. This game really picks up story wise in chapter 3 for all characters, and there's a post game boss and 4 secret jobs with their own bosses. Those secret jobs unlock after beating bosses, as well as a post game boss... And those are super challenging. I got 100hrs easily in this game and I didn't best everything.
I recommend after beating chapter 1 with everyone, then just focusing on 4 characters and beating all their chapters (2-4), then after you do, play the remaining 4 characters and beat their chapters. Otherwise it's going to be a major grind fest. Better to have better items to attach the second half of characters. Doesn't cheapen the experience at all!
Less is more. Everything you want, isn't everything you need.
