Dunkey takes a lot of things out of context or to make quick jabs for comedy. While I can understand not liking XB3 because XB3 has its issues and might just be too rambling at times for its own good, using Dunkey's video is not a good way to get an understanding of what's going on at all. I watched it and their are some clear things edited around or obfuscated to make a joke or a comedic jab at the script. Most of the things Dunkey picks on narratively make more sense in context if you just read between the lines and not just take random splices of text you take very literally. Such as:
When guy one goes "You're not enemies", and then another one says in the next scene "Next we meet, it'll be as enemies." and Dunkey acts confused. This edit ignores the fact that the second guy has had outright distain for half the party's homeland for his entire life for very in-universe reasons, and these scenes are within at best an hour from each other in-universe time.
"Cities" aren't things in this world, they're called colonies which creates a queen ant vs colony ant sort of dichotomy where you have the leaders who are literally called Queens and everyone else is varying ranks of worker ants who literally live in colonies to do the Queen's biding. So going "That's a city you dumbass." when they question what a city is ignores what's going on if that is an genuine statement and not one made as a joke. These people don't know what cities or farming is, because of the information control in both of these opposing societies.
And most of this cast is indoctrinated as fuck from birth with half truths or outright lies, so certain obvious things to us doesn't make sense for these people as these people don't even know what aging is. Pretty much everyone here is effectively groomed, coerced into submission, or just outright brainwashed in some cases to be a certain way to keep the forever war running strong. Their is a lot of information control going on in this universe and all the plebs know is they're meant to kill the bad guys or they're dead.
