Themes of occult mysticism with a symbiosis with a world going through an industrial revolution. Things that seem like obtuse incoherent 2 deep 4 u babble actually tie nicely into the story and you'll realize it by the end of the final missions. Very strong characters. Grounded, but the studio was also brave enough to try new things. Maps that incorporate lore and don't feel like levels, but rather as real locations.
It's difficult to put into words. There's just fucking magic in Thief, and in the first game in particular.
Official ranking Thief 1 > The Black Parade > Thief 2 >>>>>> Thief 3. There is no fourth game.
