Planescape: Torment

Planescape: Torment asks "What can change the nature of a man?" and spends 800,000 words answering it—a script longer than War and Peace, yet 25% more efficient than the average RPG in earning every word's place. The Nameless One's journey through forgotten lives is philosophy disguised as a dungeon crawler, and 27 years later, no game has matched its literary ambition—beating #7 God of War (2018) in narrative density by a factor of five.
