Are feminine characters what make JRPGs good? I would argue no.
JRPG characters have become so cookie cutter, you could swap any non-distinct hero/heroine from 90% of the Tales and Xenoblades and Final Fantasies and Ateliers from the past 10 years and none of them would seem out of place.
JRPGs have become so stale that outside of Final Fantasy and Kingdom Hearts, the genre is now selling sub 1mil per game.
Were there anime qualities to the classic JRPGs of the 90s? Sure. Do JRPGs need to completely ditch their anime foundations? God no. But every character doesn't need to be a copy/paste of the 10 JRPG casts in closest proximity.
By all means, give me an Amano-esque art style (I would argue that his style is not so much feminine as much as it is dream-like or "fantasy

"-like) at least the cast would look and feel different. And maybe, just maybe, by throwing Nomura out with his excessive usage of belts and zippers, Final Fantasy XVI might inspire the next round of differentiation in a genre that I hold as dear as this one.
