The only JRPG I only liked, because it was Pokemon, but than with Nightmare Fuel-like monsters.
You were this really annoying kid (JRPG, y'know...) who had to save the world from destruction (because, y'know... JRPG) by catching monsters (because... well... JRPG, y'know...) which you could subsequently and mysteriously morph with one another. You could train the beasties, and they'd get better and more powerful and, ultimately, you'd save the world. I vaguely remember there being a scantily-clad lady (JRPG.) who in the west would either be jailbait or 'totally asking for it (JRPG.)
I don't remember the name, nor was it that impressive. But man, to the little boy that was me, it was like Pokemon for... well... people who were no longer little boys. Of course, looking back it was vastly inferior to Pokemon.
Still, had some great times with that game. Oh, and the best critter (at least, it was in my memory) was the first critter you could catch (does that remind you of a certain anime based on a certain... JRPG?)...
