Chrono Trigger is a good old school RPG, With colorful characters who were designed by Akira Toryama,
If your Cool with Star Wars, There Isn’t a bad game in The Old Republic series consisting of “Star Wars Knights of the old Republic” “Star Wars Knights of the old Republic 2 the Sith Lords” & “Star Wars the old Republic MMO” All of them are great,
There is also Jade Empire if you are a fan of Kunfu fantasy it’s a bit short bust has awesome story and characters,
Suikoden is another good series though i am only truly familiar with with number 4,
And then there is Vagrant Story, Some claim this game to be SquareSoft’s magnum opus, It has a unique combat system a large number of enemies to fight a crafting system and a dark and thrilling story,
And last but not least WILD ARMS is a great series the 3rd one in particular has the not just the best female lead in a JRPG i have ever seen, but quite possibly the best main character in JRPG history, And don’t worry She isn’t your typical emotionless action girl,
