well there's also Latula's session, in which they had very few choices, either be stuck in their session forever and no one else plays SBURB again, or scratch and create a session in which the game will be won

Yeah, which is why I say they do follow a pattern, so you could definitely theorize that’s the case, but I also feel it downplays the friendships and bonds there actually are in the Beta Troll Session too.
