People love this game so much because it's the follow-up to Final Fantasy 7-10 that Squeenix never made.
11 was a MMO, 12 was a weird MMO-lite, 13 was retarded, 14 was a MMO, 15 was retarded, 16 was basically Devil May Cry x Game of Thrones with Ifrit and Shiva thrown in for good measure.
Meanwhile the other big JRPGs all went full anime, Persona, Xenoblade, Tales, Bravely Default, etc
It took 25 fucking years for someone to pick up where Square left things off with FF10, a proper ambitious, cinematic, turn-based 3 niggas in a row adventure not shackled by the safe tropes of anime.
