It was really groundbreaking to have the narrator react to what you were doing, in a “Half-Life feels like a real world that you inhabit” way. The way the music was woven into the game was also amazing, and the art! There’s a reason it put them on the map.

I didn’t like the gameplay all that much though and the world building didn’t make too much sense to me. These parts have aged the most poorly. But it was way better than just marketing.
