My fav. genre and my fav consoles for that genre. There are waaaay too many games to mention. My recommendations -and the ones I'd consider the best - in no particular order or ranking:
PS1:
Final Fantasy 7, 8 and 9.
Final Fantasy Tactis - The best tactics games of the series, still an RPG. ¯_(ツ)_/¯
Suikoden I and II - Suikoden II Is the best RPG in the history of 2D Rpgs.
Chrono Cross
Vagrant Story
Legend of Dragoon
Tales of Phantasia
Grandia
Valkyrie Profile
Breath of Fire III and IV
Dragon Quest 7
Chrono Trigger (I guess... Those cinematics are awesome)
Symphony of the night... It has rpg elements ¯_(ツ)_/¯
Alundra
Lunar
Star Ocean
A lot of these games are in the ps3 and ps4 psn store.
As of PS2:
Final Fantasy X and XII
Grandia 2 and 3... Specially 3
Suikoden III and V
Breath of Fire V (Dragon Quarter)
Dragon Quest VIII - Best DQ
Dark Cloud 2 - Somehow I think you'd like this game, its on the ps4 psn store.
Persona 4
Star Ocean till the end of time (Star Ocean 3)
Valkyrie Profile 2 - Underrated gem.
Kingdom Hearts franchise I guess.
