Long posts used to be encouraged because people got so tired of posts being a couple words, but honestly there is a such thing as too long, and in the same respect, too short. My problem in forums has always been long posts, so many times I've been in conversations and debates and everyone posts a couple of words and I post long points. There was a specific conversation in another forum that I was debating some points and I literally posted a 10-paragraph post, my average honestly is 7. I always found that to be better, and in RPGs the same thing. However, one problem is that no one feels like reading it all, so then they'll skim or even skip it and then the story gets plot-holes.
However I do want to say that even though I'm in agreement with not posting too much or too long and using pointless terms and keeping it simple, I have to point out that too short can be just as obnoxious. I never enjoy reading an RPG and one player posts a nice solid 2-3 paragraph simply-worded post and the next one is a Xeno player saying "I found the building and entered throught the air vent." It's like when I get in debates in another forum and I do those long 7-10 paragraph posts and they reply with "Good Point" or "I don't agree" and that's it. Imagine those times you text someone with a long meaningful information-filled text and they reply with "K"...
In all honesty with Xenomorphs, when it comes to communicating they can give other species a look or an emotion-intended hiss but that's it. To other Xenomorphs, then they can communicate but just don't go saying things like "Yes we should do that", just nod to them and say "I nodded and followed" or maybe "I hissed in disagreement" or "I (did whatever) as if to say no"... best case scenario, "I implied a No" or "I suggested no"
Same goes for Yautja, don't look at them a say "Nah bro" say "I shook my head" or "I growled a no"... and for the love of humanity no more "With a series of clicks and growls..." that has gotten old. Granted if an RPG comes around where yautja are allowed verbal communication, speak with some pride as if they would, no like us, these are Preds, they would sooner say "I disagree" or "Here is my plan..." before they would say "Nah bruh" or "Hey I got it guys..."
Btw... yeah, xenos are genderless... alpha-male I wouldn't necessarily see means a male that breeds with the females, it's more like wolves or even better yet like the Preds, like in AvP the Celtic, just means the strongest and therefore most-respected by fellow allies. Other than the "Queen" which is more like a leader, They are genderless asexual insect-serpents, where only "queen-status" Xenos are "fertile".
