I was just reading throught some great old threads on topics such as "scariest moment in HL2", "Most difficult level", etc. in the archives. It got me thinking about some of the game's suberb little subtleties. As I mentioned in another thread, I'm a late-comer to the franchise (having only aquired HL2 last month), but I noticed a lot of stuff on my second play through that made me appreciate it even more. Including: 1. Seeing the Citadel in the distance from atop the dam at the end of Water Hazard. I like the fact that you were mere blocks away from the Citadel a couple of levels earlier, but then travelled in realtime all the way past the industrial parks on the outskirts of the city to see the mighty citadel reduced to the size of a matchstick on the horizon. It's even cooler if you know you'll be fighting the climactic battle at the top. Sublime. 2. Finding the same creepy babydoll from the playground in Point Insertion in a nearby tenement closet in Anticitizen One. This is an awesome throwback to a very atmospheric scene from earlier in the game, and I love the idea of revisting a familiar area at a time when circumstances have completely changed. What do you reckon was with that briefcase, anyway? 3. Seeing the Antlion Guard in the shower room of NP on a monitor, prior to fighting him. I totally missed this great little cinematic of a couple of Combines getting gored in the shower room the first time I played through Nova Prospekt. Noticing it the second time, I immediately knew where the scene was taking place. Frisson by the bucketload. 4. The pacing silouette in a distant window on the menu screen for the urban combat levels. You don't suppose it's...him, do you? 5. The early meeting with a combine soldier in Water Hazard. I was surprised the see the (by then familiar) combine soldier lying dead in a puddle after I downed the chopper in Chapter 4. Then I put it together that he was the pilot and had been thrown from the wreckage. I don't know why this is so cool, it just is. Who says HL2 has no replay value, eh?
