In Samurai of Hyuga if I’m not mistaken (this have been long since I last time played) your gender has an impact on the story, especially a female, it changes the favour text/dialogues entirely (but in minor way ofc)
Like when you play as female ronin, the npc response is like: “wha—what? A female ronin?!” (considering this was set-up in feudal Japan).
Then, there is a wip I, The Forgotten One where your appearance literally altering the scene (for ex: fight scene as short mc) and choice nor npc response.
While in The War of Soul Stone is … wait I kinda forget. I think there is a difference when you play as short mc and tall mc, if I’m remember that correctly.
For example of appearance in romantic scene imagine you play as short mc—really short, and there is the kissing scene with tall RO.
I would rage if the author didn’t even bother to add little detail where your MC tiptoeing for reaching the RO—or vice versa.
It’s minor, yes, but it will be great if you added it. Readers will feel their choice is really change something, they will more attached to the story itself.
