A good chunk of the mentioned races are from the Warhammer 40k universe, which isn't exactly known as a cheery place to live in. Generally anything in that universe will either torture you, kill you, or do a variety of nasty things which make you wish they'd do one of the first two. Lots of death, war and such to go around, and no good guys either just less horrible guys, but still horrible.THEMILKMAN said:Wow, I never even heard of a third of these aliens.
And the aliens from the Aliens movies are called Xenomorphs? News to me. (Its been a LONG time since I've watched any of the movies)
The Tau for instance usually give a besieged world the choice between joining them followed by mass sterilisation and brainwashing or annihilation. And these aliens are essentially the closest thing to "good guys" in the entire universe. The rest is much much nastier.
