I feel like the MSQ of Morrowind should have revolved around the relationship betwen Voryn and Nerevar more.
Like, it shouldn't have been up to Azura and the Cavern of the Incarnate to bar the passage of the prophecised true Nerevar. That's too pointlessly direct for Azura when she's also the one choosing the Nerevarine to die in failure in Vvardenfell... Kinda fuckin pointless IMO. Should have been Voryn, instead.
He's such an under-explored villain. He's just kinda like... 'Bluh! Woe and blight upon the land I'm supposedly trying to save!' and like, there's a LOT of rich story behind his reasoning and decisions, and his worldview is NUTS, but like... You only get that by reading like 12 in-game books at the same time, and it's just not a good way to deliver a narrative. When you play the MSQ straight, it's... Very generic. Go here. Do this. Gods say do that. He's eViL. You're pRoPhEcIzEd. Go kill him. WheeEEEEEEEEEEEEEEEEEEEEE.
Like, why doesn't Voryn pester the Nerevarine constantly? He's aware of your presence on Vvardenfell, why not have him be involved more in your time? Why not have him be the reason you try to find out what happened to Nerevar (leading into Tribunal/etc)? He should try to turn you against ALMSIVI, and against the Empire.
Give us some flashbacks to the battle for Red Mountain. Tender embraces. Why is Dagoth Ur being so deferential to you? Why is he listening to you? Like you're allies? Why are Vivec and Almalexia and (who the fuck is that guy lol) talking to him like nothing is wrong? Why are we all gold-skinned? Swap between the model of Dagoth Ur and Voryn, cut between the different interpretations of the events to show the Dragon Break happening in 'real time'. Make it an actual mystery you uncover as you awaken to the truth that you ARE the Nerevarine. Make Dagoth Ur the reason false Incarnates don't make it past the Cavern. "I WILL NOT BE FELLED BY ANY HAND BUT MY MASTER, MY BROTHER, MY LOVE. I PROMISED HIM I WOULD WAIT, AND SO I SHALL WAIT UNTIL THE ENDING OF THE WORDS ALMSIVI."
Tell me that wouldn't be infinitely more compelling.
