This means nothing. There are a bunch of reasons why FF14 has a large playerbase and none of them is that the game does a better job than other especially gameplay-wise.
- One of them is the playstation-advantage. Comparable trinity-games like SWTOR and WoW can´t be played on console, which is a big thing in today´s gaming-industry. Accessibility is a huge sales factor.
- Another one is the localization. Of course it´s somehow popular in the West, but FF14´s largest playerbase is pretty much Japan-exclusive, or overall in the asian-region. And of course, Playstation is pretty much exclusive in Japan too. Meanwhile more West-orientated MMORPG´s are more popular in the West. But overall the playerbase, which wants to play MMORPG´s is much larger than the one in the West. Japan and Korea are MMORPG heavens so far.
- They cater the masses, not gamers, which is a serious issue of this game, but the most here seem to be happy with nothing but some bling-bling. Gameplay-wise this game is becoming easier and easier to the point that it just sucks. And that´s something the most mighty casuals don´t care about. They just want to press 1 button to go trough the whole game, because they just don´t care about gaming. As long as they can chill in Limsa with some glam or are able to unsync-farm pretty much everything with low efford, they´re happy paypigs. SE just needs to implement some cool animations for that 1 button and they gonna be rich af.
- COVID did a lot to gaming. A lot of ppl had nothing to do in their lockdown, so they started playing videogames. Not only FF14 has become a bunch of new players.
- Some braindead ppl followed a streamer... Like wtf?! I´ll never get why so many ppl are so easy to manipulate by some guys or half-naked girls playing games and/or talking bs in the internet. So far, it doesn´t say that the game is good or attracted millions of players by itself. Those monkeys just followed a guy "blablabla" in front of a webcam.
FF14 might be that one MMO with the largest number of active players, but it doesn´t have the largest total player number. Gameplay-wise it´s even on the bottom compared to all other MMORPG`s out there. SHB and Endwalker did a lot to make this game super braindead. While Blizzard will learn from their mistakes, other games like New World are going to improved and with Lost Ark around the next corner, the playerbase will drop again, for sure.
(Just my personal opinion, but if we would compare the number of active GAMERS in FF14 to other MMO´s, FF14 would lose hard. I would never count ppl who run through games like this like it´s a singleplayer-game, or others who just want to feel happy to show others their new glam or because someone gifted them with a new little pet.)
