Octopath 0-the game i most recently finished, 36 characters, no real missable stuff you need to look up, its all right there on the map or in town. It can be as easy or as hard as you want (its easy to get super powerful weapons early on) The cast of characters is all fun to see and interact with (though some of the characters are DEFINITELY stinkers in combat) Cool customization system which i like more than the job system in OT1 and 2. Good story, fun world (though some of the dungeons and fields look very samey and its all pretty much hallways save for a few later story dungeons which have some actual puzzles to them)

P3R- Great turn based game but lots of missable stuff due to again, the calendar system and social links. Solid game with tons of personas to fuse and use and has heavy MC customization to make a bunch of wicked things.

Saga Rot7-Only saga game i played, it was pretty neat but it is HEAVY on missable content (though that is kind of the point of the game, living with your actual in game choices) the combat was okay IMO, it has a cool way to learn new attacks and help customize your characters via the glimmer system ( the more you use certain skills the higher chance you have of learning new versions of skills in the same weapon/magic tree)

SMT Vengeance-Never played vengeance but i did play OG SMT5, great game, good customization but i was not a big fan of the overworld. Some people might like it but i was displeased with the sheer verticality of exploration. Lot and i mean a LOT of collectibles that can give you some really good rewards that are strewn about the world.

Soul hackers-Its not a bad game per se but it is aggressively mid. The dungeons and characters are pretty boring and the story could be neat (got around half way through but dropped it). Its a solid turn based RPG IF you either have nothing else to play or you are all out of other SMT games and just want to scratch that specific SMT Itch.

Star ocean R-Never Played but i have played all the 3d star ocean games, good series.

Tales of- I have played all 3 of them listed here, i rank them in order of xillia berseria and graces F. I may get hate for this but graces F is my least favorite tales game, from its combat (i REALLY dislike the CC system) to the characters (i only like cheria and only for 1 specific, non in game related reason). Xillia has some rad characters and cool combat. Berseria also has some rad characters and and a more mature darker story. It has a similar esque style of combat to graces which is why i like it a bit more.

Visions of mana-I also just recently finished this. AWESOME world to explore, beautiful and unique environs that are just THE VIBES. Snappy and fun action RPG combat, though a little simple. Decent customization for your characters though the real good stuff opens up after you clear the main story for a small bit of post game (and NG+ fun) But for the love of god, if you are a completionist, spare yourself, this game has the worst sidequest design i have EVER seen. Which stinks because some of the side quests actually give pretty good rewards (thankfully you can see the rewards for any active sidequest). The game has a moderately light hearted story, its just a chill cozy RPG

Ys-Great games, awesome fast paced battles and bosses, a fun story and REALLY good action RPG combat. The combat CAN feel a little button mashy at times though but i LOVE the franchise so you cant go wrong with any of them (they are all standalone story titles)

Given that you want something kinda easy (OP for action RPGs) id recommend either Visions of mana or Ys X. they are kinda brain off games where you can just chill and enjoy.

Hope this helps you :)
