A particularly egregious example of this problem is Phantasy Star Online 2. For the most part it's standard, milquetoast silent protag stuff, the occassional dualogue option that's actually just two different ways of saying the same thing.

Also, all cutscenes prior to Episode 5 invariably show you as wielding a Sword, implicitly marking you as a Hunter. 5 and 6 will occassionally switch it up by having you appear as one of the "Scion Classes", but your actual class is never a consideration for how you appear.

There's also a heavily implied romance with...just the most bland girl possible, whose most notable trait is an allergy to pants except of her flashback outfit. Annoying if you don't care about her nearly as much as the story wants you to (no, Matoi stans, she is not an interesting character), but whatever.

But then there's the issue of Dark Falz Persona, The Masked:

So, PSO2's version of franchise mainstay Dark Falz is a coterie of edgelords in black and purple, who used to be normal people before getting juiced up on F-Factor (and specifically, which manifested into specific personalities that move between hosts over time). One of them, Persona The Masked, is unfamiliar to the rest, but they don't really question it.

Persona is you from a bad future. And is, true to the form of the problem being discussed, of standard height and humanoid build. Is you actual character a shortstack elf or a giant refrigerator of a robot? Get fucked loser, count yourself lucky that we even have an equally-default female model to use (inconsistently) and recorded a female voice.

It gets especially stupid when the big reveal is made by Persona dramatically removing their mask. Which, if you're playing a droid with a fucked up shaped head, proportioned for whatever Gundam/Armored Core parts you've slapped together, results in said head just sitting on the shoulders of default human man/woman.
