Half-Life 2: Episode One
Episode One is the continuation of, in my opinion, the best first person shooter of all time. The gameplay engine remains simply the most enjoyable to just run around and shoot things in, and Valve's level design is impeccable. Everything here is created with the intention of making a good video game combined with a strong narrative experience. I love the way Half-Life presents its story, it's just a much more immersive world than almost anything else.
I miss exploring the wide open countryside around City 17, and the game is a bit short even for only being 1/3 of a game, so it might not have been as good if it weren't for one thing - Alyx, thanks to a combination of great voice acting and the best facial animation I've ever seen in a game, is one of the most endearing and likable game characters ever. I really care what happens to her, and it wouldn't be the same if she wasn't around, watching my back. This is one of the times where graphics actually matter in pushing a game over the edge. I can't wait to battle Hunters out in the wilderness in Episode Two.
