Everything Amano makes is blond. The guy has a clear fetish.
And Akihiko Yoshida has a thing with thighs, and Tetsuya Nomura with stylized clothing. Every artist has a sensibility towards something in particular, that's hardly something to make a big deal out of.
Nomura's clothing disturbs me enough to bitch about it. Blonde and overtly blonde I can take. Thighs are fine. But Normura's space-balls style of dress up is just too left field for me.
I can appreciate the aesthetic of his style well enough, I'm not saying he is a poor artist. Far from it actually. In fact there are innumerable artists that I think are fabulous in their own respects. The fact alone that an artist can render beautiful art does not, in my opinion, translate well into every setting and RPG.
It is a purely subjective matter. Not an argument anyone can win really. All I am saying, while the subject is on the table, is I can really see how Nomura's style (being so different) can prove either a real draw, or turn off depending on both the setting/game in question as well as the given gamers tastes.
Whenever I see any Normura character/clothing/setting I feel like I am viewing a super-deformed sci-fi, hip-hop circus. Cool to look at. I would probably love it in an anime or movie. But I don't like sci-fi and have no particular affinity for the circus nor hip-hop and it greatly inhibits immersion for me.
Truly I would take 16-bit sprites, that leave more to my imagination, than a Nomura-heavy visual influence in my RPG's.
