I found Flow SMP and it is a scripted Minecraft SMP that is all about story.
It has deep lore and wars and alliances. People can play villains or heroes and there are mystery characters too.
The whole point is betrayals and plot twists. Everyone gets a role in the story so it feels like a big ongoing series.
