I’d honestly like to see more variety in general instead of every cast looking like they came out of the same character generator preset pack.
More middle eastern, african, south asian, latino, mediterranean, mixed-race characters, different body types, different facial structures, different hair textures, all that stuff. Not even in a "forced diversity" way, I just genuinely think more visual variety makes character designs more memorable.
A lot of VNs already blur together visually after a while because everyone has the same pale skin + tiny face + identical proportions combo. Then one character shows up with a unique look and suddenly my brain actually remembers them 3 weeks later.
