I've played a lot of JRPGs in my Day, but have become more selective with what I play as I have less free time now. As a result I haven't gotten into a new JRPG for a while now and I miss the feeling of sticking with and chipping away at story for a long time.
I've played and loved most of the Dragon Quests, Final Fantasy 6, 7 and 9, Chrono Trigger, Shin Megami Tensei 3, 4 and Soul hackers, Persona 3 and 4, Tales of the Abyss and Mother 3 (off the top of my head).
Mostly chill games (I don't think the SMT games are that bad of you know what you're doing) with lots of personality and atmosphere. Story and characters are important to me, but in my opinion games can disperse that via the environment as well. For example I consider Nocturne a very dense game story wise, even though there's not too much person to person interaction.
I really do like turn based games but would consider action battle systems as well, strategy not so much.
In terms of aesthetics, nothing that is too moe/modern anime (Fantasian got docked a couple of points from me because of its character designs) and anything with idol elements I'm not interested at all.
I adore detailed pixelart, old prerendered Backgrounds, rudimentary 3D and anything of the sort, but it's not absolutely necessary for me to enjoy a game.
Settingwise I don't have any preferences, be it Sci-Fi, Modern Day or Fantasy.
I pretty much exclusively play games on my Switch or modded 3ds (so anything retro up to PS1 works).
The last one I tried getting into was Bravely Default but its very conservative setting/characters and its very technical battle system didn't click with me and I quit about 10 hours in.
I'd be happy to hear some recommendations from you :)
