You mean the non-ending where the old woman explains everything that was supposed to happen before they ran out of budget?
I don’t think budget was an issue. Lucasfilm set ridiculous milestones/deadlines/weird last minute changes for the game’s completion. That studio, Obsidian, still showed heart and care into their story/characters. Besides, years later of fan dedication did that game get a majority of its content restored. However, I understand many still dislike the ending for still feeling rushed. Still, KOTOR II’s ending felt similar to ESB, which I adored. An open and uncertain ending.
Lucasfilm at the time was great with their gaming success as they were with their films. Not well, obviously.
