That's not exactly a bad thing if you ask them but if you don't like the feeling your free to play other Japanese or Western MMOs that still get updated on the regular bases and I would love to recommend one except that they no longer exist. Your options are either WoW, FFXIV, or the plethora of P2W Koreon MMOs that somehow still get made and come out to this day.
Just wanted to clarify, I'm not saying I dislike FFXIV as I had fun playing the game and it deserves it's spot as one of the big 3 MMO titles of the past decade(and this is coming from someone who has played a ton of MMOs). My post is more of a warning to people here who are going to try this out on Xbox with a controller. I'm saying I
highly advise against using a controller for this particular game, because the controller
feels much worse than KB+M for this game.
A lot of people don't remember, this game was technically a PS3 game, and most of the PS3 MMOs out there(the few that came to that platform) controlled really, really poorly or had massive amounts of input lag, terrible deadzones, and really bad ways of translating KB+M to controller in an optimal way.
It wasn't until mid to late-PS4 gen that MMO controller players finally saw a hint of light at the end of the dark tunnel of bad controls, with devs finally utilizing them correctly and taking controllers seriously so that the audiences for this genre can expand more.
Regarding the second part of your quote, there are a new wave of MMOs coming(from the east
and west) and we have to see how they perform. I enjoyed Wayfinder closed beta and I'm looking forward to the full release later this year as it played amazingly well. Dune: Awakening just showed footage of their new MMO and it seems good so far. The ESO guys are working on a big new I.P. as well and will be announcing the project sometime soon. Path of Exile 2 looks way better optimized for console controls than it's predecessor. The new Vindictus sequel trailer looks incredible. Soulframe(from the Warframe devs) looks promising as well. Chrono Odyssey Soulslike MMO(why didn't anyone think of this) looks really promising. Light No Fire looks amazing too.
These games exist and are coming out. We have just had a long interim of time in the past few years where a lot of these devs were silent, because they realized with the recent MMO failures that you can't release a game with half-assed content, half-assed post-launch content, and a bad gameplay loop.
