Chrono Trigger is one of my favorite games of all time. It has a great and colorful cast, one of the few time traveling stories that actually makes sense, and very fun gameplay in the form of the combo attacks. It's really the only RPG that I genuinely enjoyed every character in my party and wanted to use them all. That, and the choice oriented story, producing a plethora of endings, was unprecedented at the time and gave it a ton of replay value (along with it's introduction of the New Game+ feature). Awesome, awesome game.
I'mma let you finish later Golden Sun but Chrono Trigger is one of the best RPG's of all time and gets my unwavering support here.
