JRPGs aren't dying. With that said, I'm not pleased with the general state of the medium.
I dislike that the once fairly even balance between Action/RPG and turn-based/RPG releases is now heavily skewed towards Action/RPGs.
I dislike that we're back to having to beg Square-Enix to release games in English that aren't numbered Final Fantasy entries. I mean, come on, if you can't make money with Dragon Quest in the West, you're doing something very wrong.
I dislike that most lower budget JRPGs heavily cater to Japanese otaku which means creepy underage sexuality.
I dislike that most turn-based JRPGs are dungeon crawlers.
I dislike that after being on fire during the PS2 generation, Atlus stumbled with the next generation. At least Radiant Historia was awesome.
I dislike that after a quick turnaround from 3 to 4 (about a 2 year gap), there's been about a 7 year gap between Persona 4 & 5 during which time the series has been milked to death with remakes, TV series, movies, fighting games, cross-overs, and even music games, and in fact everything EXCEPT Persona 5.
I dislike that the mid-tier is pretty much gone outside of Tales unless you're generous with your definition and also include lower budget fare like Atelier, Disgaea, and Falcom's games.
I dislike that after getting off to a promising start with Blue Dragon, Lost Odyssey, and Last Story, Mistwalker jumped on the mobile bandwagon instead of further perfecting their craft.
Now don't get me wrong. I like Action/RPGs. I like dungeon crawlers. I like Atelier and Ys and Kiseki. This year is shaping up to be one of the best years in a while with games like Persona 5, Xenoblade X, and Trails 2. But I definitely miss the PS2 era when interesting mid-tier JRPGs flourished and being turn-based wasn't considered taboo or a design flaw.
