Oh god, there's so many choices to sift through. I'm going to go with Silent Hill 2, which was an all around beautiful game as far as I'm concerned. It was the first game I've played with (I think) really great voice acting. Sure, it was stilted at times, but when you hear the full letter read... it hits. It still looks good visually, the story probably had the most depth in the whole series, nice soundtrack. Mmmhmm, goodness.
