"Species that don't change die. We've lost our way. We've allowed our predatory instincts to dominate us. We disperse ourselves throughout the quadrant, sending ships in all directions! We've become a solitary race, isolated. We've spread ourselves too thin. We're no longer a culture! We have no identity!"
I haven't spent much time with krogan before, Wrex, and I have to say, you're not what I expected. Wrex:
Right. Because humans have a wide range of cultures and attitudes, but krogan all think and act exactly alike
The crew of the Enterprise discover a totally new lifeform which turns out to be a familiar old lifeform wearing a funny hat.
Most of Israel’s critics, especially abroad, see the country as a one-dimensional monolith. As they see it, all its (Jewish) citizens are marching in lockstep behind their rightist government, consumed by a dark ideology, supporting occupation and settlements and committing war crimes. This, by the way, is a mirror image of the admirers of Israel in the world, who also see Israel as a one-dimensional monolith, with all citizens marching proudly behind their brave and determined leaders – Binyamin Netanyahu, Ehud Barak and Avigdor Lieberman. The truth is far removed from both these caricatures.

Nonhuman fantasy races tend to have their differences from humans defined not just physically (pointy ears and what have you) but psychologically. You might think this would entail making them really alien but that's difficult and often winds up making them hard for the average reader or gamer to relate to. What it more often means in practice is that members of the imaginary race wind up all sharing certain personality traits in common. ALL elves are tree huggers, ALL dwarves are dour, stubborn, and acquisitive, etc.
And that makes it tough for the writer to have the critters seem like there are significant personality differences among them. I know, I was constantly trying to solve this problem while writing my drow novel.
That, I think, is, from the author's point of view, part of the appeal of what I call Chinese menu fantasy, where the Tolkienesque band of protagonists has one archetypal elf, one archetypal dwarf, etc.
It's much easier to make the characterization work. And I'm not denigrating this approach. I wouldn't dare, now that I've done the diverse band of heroes myself in my dragon thingie.
Of course, there's at least one other advantage to this approach, also. Frequently, much of the point of a fantasy is to give the reader the chance to explore an exotic imaginary world, and by giving him extended commerce with characters who represent many of its races and cultures, the writer facilitates this process.
''Remember: one culture per alien planet. More than that, and you're just showing off.
