What's your favorite VALVE game?
For me, it'd probably be the original Half Life as well. The mix of action, platforming, and puzzle solving blended excellently, and the environments were really atmospheric and well crafted, and I really liked the way it told the story and progressed through the experience without cutscenes or much in the way of loading screens. A very immersive and thrilling experience for the time. (Even if I did get in on it much much later than most XD)
