Tales of Eternia(Destiny 2)- The best Tales that I got to play AND understood; until the real destiny 2 comes to western region, this is the funnest tales that I came across. As a bi-lingual myself, I clicked with Meredy. It's nothing innovative but the levels of detail, balance, and combat in this game are top of its league.
Terranigma- I cannot pick any major flaws in this game whatsoever, although it does have some rooms for improvement. This game sheds some interesting viewpoint about history, environment, and religion, and it did it without going emo(thus making it only one of its kind that I've seen).
Pokemon Red/Blue(and their remakes Fire Red and Leaf Green)- RPGs don't have to be about saving the world and this game proved it. Nintendo went back to basics and made a rare case of turn based, random combat work.
Tempest: War of Genesis Side Story 2- This game has an unmatched, super flexible growth system. You don't even have to go through battles to grind characters, making the game as short as 7 hours if you choose to play that way. The full game is about 50 hours for me usually(out of 15+ times that I played). Softmax needs to step it up and properly remake/translate the game, it'd make a great PSP game.
Diablo 2- single player side of the game is flawless. It's the bnet side that ruins the game, and I can choose not to play the game that way.
I have more games that I play regularly but I had to chop my list down. I figured nobody would want to read due tl;dr
