Well, if that's so, then playing elves or dwarves, or asari or turians in Mass Effect, is just as boring
I confess I haven't read every word of every reply in this thread, but am I really the first to point out that we can only
wish we could play an asari or turian in any existing installment of ME (PC mods and Andromeda rumors notwithstanding)?
Meanwhile, what I don't understand is why people find it important, because in my view, it is a completely superficial feature! Every character we play, human or not, is, in spite of a non-human label that was attached to them, still human in everything but name and appearance. And that means, human in everything that counts.
TL;DR Asking why people are so passionate about playing fantasy races or aliens is like asking why people like to dress up in different costumes for Halloween or Anime Expo. Why doesn't everyone just go around in their Sunday best?
Is this a situation unique to video games? That's rhetorical. Can you think of any examples in popular media (by which I mean TV or movies) where, the superficiality of "others" just being humans in window-dressing, is not the case for a heroic character that has dialogue? I use those qualifiers with care -- we have plenty of examples of inarticulate forces of nature (the alien in Alien) or laconic menace (the aliens in Independence Day), but for heroes or even sympathetic characters that have something to say, not so much. I would argue that even the excellently novel aliens of District 9 were "just" mirrors of the human condition.
Even in literature, which has a lot more license despite the miracles of CGI, examples of truly "other" heroes that talk and interact with human characters are exceedingly rare. And how could it be otherwise, given that such books are written by humans?
And that's the point. The folks that write the stories behind the video games are humans, catering to a human audience. So of course all the fantasy races and aliens are going to be humans in window-dressing. That's not a bug, that's a feature! It's the window-dressing that allows us to experience an aspect of the human condition that might otherwise be hidden.
