I just finished it and overall it was an excellent game. My only complaints are the stuttering that I encountered a bunch of times throughout the game and the way they left me hanging at the end without an explanation. They build up the story throughout the game and they don't even wrap it up which would be nice if half life 3 was coming out next year but I suspect it won't be coming out for quite a while. Some sort of weird twilight zone type ending left me feeling that the game was incomplete. Other then those 2 complaints the game was great.
