Yeah the environments are alright in SMT IV but I can't stand the character models, they just don't look good to me all(I think it's the art). I definitely think that Nocturne looks better in motion on my CRT though.
Nocturne's art style carries it extremely well. Perhaps more so than any other Atlus game on the PS2. It's understandable how you could think Nocturne could look better, even though its objectively worse in the areas that can be compared.
