I went through the "bored with JRPGs" faze as well.
I was super into them on the NES, SNES, and even into the PS1. But then I just got burnt out on them. And the PS1 had so much freaking variety since developers were still getting the feel of 3D gaming, that there was just so much more interesting stuff to explore.
But recently, I've gotten heavily into them again, starting with going going through the entire Dragon Quest series, then moving on from there. Mostly, though, it's because I have a lot of downtime at my work lately, and JRPGs are fantastic time-killers.
16-bit beat-em ups are becoming hard to go back to, now. I used to eat them up as a kid. Played them all and loved every second of it. But now when I go back, it's just repetitious and boring, and it usually gets me a little sleepy.
