I've always thought the scariest parts of those games were the first 30 minutes and then no moment after. On the contrary, Silent Hill 2 makes you wallow in silence and dread so that by the time it finally breaks in its final third, and the whole thing becomes a cacophonous nightmare, the sound is overwhelming.
Silent Hill 2 is often considered more depressing than other games in the Silent Hill series due to its deeply introspective and psychologically complex narrative.
