Left feeling a bit empty after playing it for the first time a few months ago(why did I wait so long?) I am afraid no JRPG will be able to surpass it. Would love to have a discussion about similar games that reach the same quality level (Note: I have already played Final Fantasy VI ).
I'm at the final boss of Super Mario RPG and can vouch for it being really fun. While it's not as epic in scale and story as Chrono Trigger, it's got good humorous writing, good pacing, and the difficulty is just right imo.
I also really like that if you lose a battle, the game resets you at your last save point and carries over any exp you gained, making grinding way less tedious.
