Adventure game fact: The Secret Library Archive Project contains a version of The Curse of Monkey Island with an extended ending.
The reason it was deleted from the “normal” version wasn’t budget constraints, as usually claimed: it was that LeChuck throws Elaine into Big Whoop during the intro to Part VI, turning her into a rotting undead corpse. And she stays that way.
This was foreshadowed back in Part V, when Guybrush says to LeChuck, “But if you kill Elaine, won’t she hate you even more?”
(This is also why the CMI Official Strategy Guide prints the lyrics to the end-credits ballad “Plank of Love,” but not any of the storyboards.)
