- Baby's first JRPG/visual novel. We've had an entire generation of people grow up having never been exposed to a high production value JRPG before so they are getting mindblown by their first exposure.
- Later on the game increasingly panders to tumblrites/redditors with the protagonist worship, feel good stuff, dress up, etc.
- The state of the RPG genre is abysmal. We haven't had a big budget high fantasy RPG since the Witcher 3 almost 8 years ago, so people's options are limited. You either play WoW/GW2/ESO/FFXIV, lower budget JRPGs like Trails or Tales of or Atelier, or you have to play old games. Or you accept that the state of high production value, audio visual high fantasy fiction is just in a really really bad place and find other things to fill your time with.
Also, it should be noted that the state of music is really bad. FFXIV is a lot of people's first exposure to a decent soundtrack. Or at least, it was. Not fond of the soundtrack being increasingly dominated by pop songs as of the last two expansions. Still better than almost everything you hear in a Western game, though.

Also, the game does look overall pretty enough, at least in cutscenes where you get to stare at your character model with proper cutscene lighting applied on him to make him look good. The characters look attractive and the armor designs are nice. Nice spell effects in cutscenes. The game does have graphical issues (poor lighting issues and shadows outside of cutscenes, low resolution ground textures, etc). No matter how much people have recommended ESO to me, the plastic looking characters and the ugly armors and the environments and overall look of that game are a dealbreaker to me. GW2 doesn't look bad but it usually doesn't look very pretty either. Most MMOs look hideous. SWTOR, STO, Rift, LotRO, etc. FFXIV is perhaps the nicest looking high fantasy RPG in recent memory behind WoW and Trails/Atelier, but again that's more indicative of the state of the genre. So you're back to people's choices being limited.
Another appealing thing about FFXIV is that you can comfortably play it with a controller. Once you experience it, it is hard to go back to mouse and keyboard, and the controller and camera mods for WoW and GW2 simply don't compare.
