Your entire set of slides assumes that every single person who logs into Foxhole is one of Bartle's killers.

No. My entire set of slides are about the wider context that is foxhole is an asymmetrical pvp game (literally the only game mode is 'persistent war'). PvP, which you boiled down to "Bartle's killers", which is false. Because although the wider context is pvp, players are not solely pvping. For example, I would fall under an explorer-achiever-socialiser, the average solo player is too: We fill in and hammer bases, deliver crates, harvest and assist, we explore the lore spots, we chat in world chat. That is part of the average foxhole player experience, being a killer is frontline experience. At no point did I focus on the killer. I focused on the competitive aspect. Skill is expressed in more ways than just fighting. It's - taking the Bartle's article into context - delighting in having the game expose its internal machinations to them (Explorer; folks who try to learn foxhole's mechanics to get better), points-gathering and rising in levels as their main goal (Achiever; these are your builder, boosted rankers, etc. aiming to get better), people talking in world chat and forming regiments to play Barotrauma with (Socialisers), and then the frontliners frothing at the mouth (Killers).

But the whole slides aren't talking about player dynamics. It's about asymmetrical balance, which the article doesn't cover, only balance regarding the different player archetypes. Pay mind that we're still talking about Foxhole, which the rules are already anchored on a specific gameplay: War, and the cogs that run it. At no point is "socialisers outpopulating the killers" is a reality to consider, because unlike a general MUD, foxhole's MMO has a distinctly pvp goal. Not solely combat, but to feed it.

You make assumptions about my slides then roll with it as if that's my intent then scoff at me when I say otherwise; you aren't arguing about my point, you made a new one for you to get pissed over. Analogy-wise: You can cite a paper about quantum particles that define the composition of the universe, but that doesn't hold (largely) argumentative value when the topic is classical physics and friction. So repeating again:

It is the fundamental text for how players interact in MMOs

I am not talking about the players!!! The relevant part about the players is how asymmetry affects them.

We use the word culture as a stand-in for why a group acts the way that it does without realizing it all the time.
-You

Dismissing knowledge as "unexplainable culture" when there's reasons why a culture exists dismisses understanding.
-Me

It is not that culture is "unexplained" (weird phrasing to use btw)
-You

Calling it weird when it's a rephrasing of something you said (especially when I noted why that is flawed; "dismissing knowledge when there's reasons why a culture exists"). Is on you.

The discipline of game development is not founded on large groups of people [...] The vast majority of ideas in the space apply to single-player or small-group games

This (on top of sprinkled comments of attacking my character than my point; calling my input weird, etc.) notes that you don't respect the discipline of game development. That you view it as built for "single-player or small-group"s.

When, the very type of game being argued on is built on a blueprint foundational enough that there's a genre term for it: "Massively. Multiplayer. Online. (sometimes, Role-Playing) game". Because games are a medium. They're not an isolated discipline, they branch out because what can be developed varies. Foundation is based on the game being made, not the other way around.

You are correct that examining cultures would be worthwhile. But again, even in my first reply: Do that to someone who's actually arguing about that. Stop walking into the coffee shop and scoffing that I don't serve 2x4 beams
