Half-Life was pretty much my first hardcore shooter. I played that whole franchise in the course of about a week. Before then I had only ever lost to my brother at Halo 3 and Call of Duty 4 multiplayer. After that was when I started playing more campaigns instead of just the multiplayers on shooters.
