Another thing I found great about this game is how you identify with this guy, faceless save for the box art or any fan pic in which he is always holding the crowbar. By making him late in the beginning of the game and giving him the option of turning on the security alarm in the reception area makes him a guy like you and me; even though he works at a top secret government facility, it's crappy!
The Bad
Even though it tells the story well it really doesn't make much sense. So who is this G-Man guy? Why is he always behind bulletproof glass? How can this Gordon Freeman guy be late for work in the beginning and in the end be taking down highly trained extremely dangerous army operatives? Doesn't it cost a fortune to run (and clean) Black Mesa? Isn't it so big that you can see it from outer space, let alone at the side of the oad that borders it?
