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 ).
Suikoden II is generally considered one of the best JRPGs on the PS1, and while the English translation isn't spotless the writing and setpieces have a similar quality to Chrono Trigger. It is a sequel to Suikoden and you'll enjoy the second game a bit more for having played the first one, but it's not a requirement. The original Suikoden wasn't nearly as polished and I'd hate for you to give up on Suikoden II because you burned out on it.
