>>67017762I second the Rust mention as a miniature story arc, a hero's journey. Though you actually need to be a member to see the hero's lowest point. And climaxing at season 3 finale.
But to go broader you can't go wrong with minecraft, especially collabs. Minecraft captures the heart of a streamer. It's sort of an idealized, anime kind of history of her time but I think it's neat to go back to say her early building streams. The fifth gen introduction. The HnK day. The first corp era with all it's drama like Pekora making a fumi-e out of her head. Her getting into the note making business and that stream with Marine is a highlight too. The Coco grad era and the last hurrah of 4th gen unity. The upa and school building era, the lone wolf era, the new world and kanaken era.
And of course there are sports festivals and summer festivals. The first summer she hung out with Rushia the whole time, that's a crazy time capsule.
You can see lots of different shifts over time just watching minecraft.
Also just remembered this stream that will give you whiplash. Nothing else better says change over time like that one.
