I can never decide if I want a Game or Movie to go into it all, If they reveal and show us everything it would completely eradicate the mystery of the Yautja. So I'm going to go with no, I'm curious as hell about it all but curious kills the cat, it's like Master Chief's face, I'm curious as all get out, but it's better we don't know.
I too am partial to it though, a "Council of Elders" so to speak and different societies branching into different clans, and the idea of rogue groups, heretic outcasts and Individuals. This honestly is what's so great about Yautja, to a thrid party of casual gamers and film goers that say "Oh the Predator was so cool with his creepy face and his arm knives things and the gun, turning invisible and sh!t, it's badass!" but they don't realize that just watching the first movie alone gives so much imagination to them. They clearly are advanced, have a sense of honor and respect, they are civilized and hunt for sport and collect trophies to prove themselves, his pod came from a larger ship meaning he was a part of a group, others had arrived before meaning it's a systematic thing, and the nuke shows that they will do anything to remain a mystery and take everyone at threat to them down with them, and I think I just barely made a dent into it all, and most movie goers don't see all this, they just see an alien monster that kills people.
So obviously I like that we have seen more of what they're from and the fact that we have a good idea of all the mysteries and secrets, but don't blatently show us everything in detail right to our faces, other than books and comics at least the films and games in my opinion have given us the perfect amount of information.
Note, I'm really really not a fan of the comics and books, just the movies and games and other extended universe you can explore via the web, the comics and books just in my opinion are fan fictions that aren't worth looking into.
