In my case, it’s quite the opposite. Everything about DQ3 bleeds Dragon Quest. If there’s one game in the series that I feel captures the DQ charm perfectly, it’s DQ3. Well, 8 too, because 3 lacks the party member interactions.
You probably feel this way, and I don’t blame you, because it’s hard to make an 8 bit game (and a strict recreation in 16-bit) have expressions in the characters.
Also, playing devil’s advocate, but they wouldn’t give more expressions to a character that is supposed to play “you” (or vice versa) if they don’t need to. It’s like their design philosophy.
I haven’t really seen any main character be expressive tbh. Eight and Luninary are probably the only expressive ones.
As for design... well, it’s all subjective, but I find Erdrick’s outfit and accessories to be iconic. That tiara alone is emblematic.
And on a personal level, Toriyama artwork is quite the opposite of “generic”. I don’t understand why people keep saying it’s generic. It’s extremely distinctive from every other anime/manga artist.
From clothes, to hair, to eyebrows, to accessories, to vehicles, to monsters, to robots, etc.
