There a couple very specific eras of JRPGs that hold a very special place in my memory.
The Super Famicom era around games like Chrono Trigger is the peak for me though. I remember I got it as a gift totally by mistake, my parents had meant to buy another game but got possibly my favourite game of all time instead. I can still go back and play that game and it holds up just fine.
PS1 era Squaresoft was also pretty much a golden era for me, Xenogears was a pretty massive influence on some of my younger intellectual development.
