I'm pretty heavily invested in trying to comprehend the human condition, and I tend to find the portrayal of beings in fiction quite lacking in terms of nuance and reality. Even if it's an alien - because obviously they're based on what the writers have experience with, which can never be an actual alien.
Oh, I've tried giving up making sense of it all and I'm much happier for it, because it doesn't make sense. There's no meaning in life or existence. But do you believe that the effects of the environment on evolution would be so great that the resulting lifeform would be so different from life on earth that there is no resemblence? How can you be sure?
In any case, having aliens that you cannot relate to in any human way would not be good for fiction. I can't see how that would make for an enjoyable character. I'm sure someone will try to prove me wrong with some sort of reference.
The character of Wrex, for instance, is apparently very popular - but I think he was one of the most boring and predictable characters, but most Bioware characters are - in my experience.
Yeah, don't care. Romance stories are predictable. Avatar was predictable. Couldn't really handle those, because they're not
my kind of predictable. I mean, if I'm into something and enjoy it, just give me more of it! I don't need every game to be totally new. Just new
enough.
I never understand reviewers who complain this or that mechanic is "dated". If it worked then, it works now. Yeah, I don't want to have the feeling that I've watched the story already before (Avatar), but use some recognizable elements? Sure.
I did like Wrex better than the new Krogan in Mass Effect 2, though.
