While I am sure that there is a significant portion of players that feel this way and think character creation is a pointless chore they’d rather not suffer through, I simply disagree.
Being able to make the choice to customize my character is important to me, even if it is never referenced later. Nobody cares what you look like in Baldur’s gate, Cyberpunk, Divinity, Dragon’s Dogma, the Elder Scrolls, Saints Row, Elden Ring. Does the fact that nobody references your pink hair or ridiculous proportions mean that the customization is pointless? Not to me.
Letting me choose means that the game is going to honor my choice, that my mental picture of the character is going to be consistent even if never referenced (it would be strange to ask my hair color and then later mention it being a completely different color without justification!), and I’m not going to get through half the book and suddenly be told that I’m shorter or taller than I expected or have some other contradiction to my conception of the character throwing me out of the experience.
Skipping over the choice leaves that ambiguous.
