I can see where you are coming from in terms of HL1. I really can, but that was 1998. Half-life 2 has a fantastic story with dialogue that walks over a bunch movies. I love it, and whilst it certainly uses an old concept "alien invasion of Earth" (alot of movies, books and so on have also used this) but it's how it handles it - and it handles it wonderfully. It's original and striking and it's a step in the right direction for video gaming.
