I don't agree with that comparison at all. From a gameplay perspective, FF7 Remake is pretty great while FFXIII is bad and FFXV mediocre to boring. From a story perspective the remake is mostly that of the original, which is great. FFXIII and FFXV were mediocre to boring on the story front from what I've seen. I've never felt compelled to finish either 13 or 15 but I easily finished the remake within a couple weeks. FF7 Remake has some significant missteps but they bear no similarity to those of the other 2 games so I see no reason why there would be a correlation in disliking them.
