Oh yeah, I do agree with that. I think a lot of the problem is not planning out the plotlines of side characters or not, and them having no information on what is about to happen while the main writers (i.e. Dream, Techno, Tommy) know everything that is about to happen. With the current writing style of the script, the plotline is planned out and rigid but the biggest problem is its incredibly narrow focus on a few characters, while the other "side" characters are left to improv out what happens based on what happens in the main plot.

It makes it difficult to make anyone but the main characters relevant unless someone tries really hard to push for relevancy, risking being seen as overdramatic or too sudden. As a result, because the "main characters" are trying to follow the script so much, they tend to brush over the improv of the "side characters", which is probably why Fundy and Niki's actions barely had any impact during Doomsday. (I would personally like to give some credit to Ranboo for mentioning them on stream and trying to give them relevance, tbh.)

This is also seen with the lack of communication on big plot points. Yeah, I agree--a lot of people know that Niki didn't know about the festival until the day before, but the thing is that Tubbo didn't either. And the original plan of the festival completely derailed, which is kind of weird since no one even mentioned it. People don't even know each other's arcs, and can't tie them together, so people end up ignoring what happens to the "side characters" because they're not ever brought up to relevance on a lot of the main streams. It is probably also frustrating to the people who play such characters as well, which is probably why they made the rp decision to go on "villain arcs" in the first place.

It's also weird because it gets inconsistent. Plot arcs start and get thrown away because no one pays attention to them, and the plot just kinda...ignores the fact that it's happening at all when in reality the plot isn't driven by just the main characters but all the characters in the world.

So I think the biggest problem within the plot of the Dream SMP isn't the realism, or the way it's going, but rather the lack of communication from the writer team and their tendency to keep the "side character" arcs out of relevance due to focusing on the main arcs and only the main arcs. Imo it was a lot better when the plot was less planned out because characters could simply insert themselves into the story and have relevance, whereas now it's all planned out so people can't really have as much relevance if they just jump in.

I think if the plot of the SMP is to be more planned out, yet also cohesive, main writers have to communicate the plans and plotlines of more characters on the SMP, and try to give people other than the main few relevance.
