For awhile my list would have been topped by FF7, FF6, and Chrono Trigger. Played 6 and CT as a kid but couldn't get into either, I got really into FF4 but gave up against the final boss. I'll fix that later this year
Finally got my hands on FF7 this year and it quickly became the best JRPG I've ever played, finally got around to beating FF6 the other day and I enjoy it way more now than I did as a kid
1/4 done with Chrono Trigger, that's next.
Otherwise, beating the OG Zelda is up there, maybe even OG Metroid
