KOTOR, both of them but especially the 2nd are built on concepts (post-nihilist existentialism amongst other, to me it's the most obvious) that drive the story. I feel like nowadays, AAA games want to avoid philosophical stuff, or rather keep it way too simple, and we have shit stories (fallout 4/Skyrim. An exception though for Fallout 4 Far harbor DLC).

But we still have good non story-driven AAA games.
