9/10 Sounds similar to another post about the Tsukihime remake. Still great but more like a "I feel like I've already heard this somewhere already" great.
I think Bravely Default 2 is a good JRPG but I think what will push it as a great JRPG for some people is the music! The music is so good. There are times you want to quit the game, some bullshit moments here and there, and the story is your basic Final Fantasy adventure around Crystals but the music will keep motivating you forward to see what happens next, making your average Final Fantasy crystal-macguffin plot more epic than it really is. I give Bravely Default 2 a 10 out of 10 for having great music. And it also comes with a free game!
