One of the reasons why we trimmed the epilogue is because we were afraid the ending cinematics were becoming too long and would detract from the epicness of the experience.
... ... huh. I guess Larian's devs are not fans of how Peter Jackson (or JRR Tolkien) ended The Return of the King. I mean, many critics and fans also weren't happy with the finale(s), so it's not an outrageous position to take, and I can see why you'd prefer a big finish. But I liked the 20 minutes of fake-out endings and the Scouring of the Shire. Sauron's fall was just the very beginning of the end. Heck, Sauron didn't matter to me, really - everyone and everything else did. It's the same here. I'm glad this is being addressed, at least somewhat.
But LOTR is a movie, not a game. Even if you watch the extended editions of the entire trilogy, that's still under 24 hours of content, I believe.
That's nothing compared to the 100+ hours you spend in Baldur's Gate 3. Also in the game, YOU roleplay as the main character. These are YOUR relationsships and it's YOUR story.
A video game, and especially a good RPG, makes you much more invested in the characters and stories than a movie.
