There’s a game called “Rust” in which you play a character in a wilderness. When it first came out, everyone was assigned the same avatar: a white dude. As we all know, “white dude” is the default everywhere, so no one complained.
Then, in an upgrade, they added other avatar options: different faces, different skin color. As an interesting experiment, these options were not under player control: they were randomly assigned. White dudes logging in suddenly found that their avatar might be a black dude (still a dude, at least; female avatars aren’t yet available).
