OK OK. Half-Life games are the best shooters ever made.
Talking of shooting, did you know that in 2010 alone, there were 675,964 gamers, who prefer shooting games to actually being shot? The irony here is that according to the IGN, and their data has been verified by me, playing shooters carries more of a health risk than being actually shot. This may seem a tad strange, but have you looked at the statistics showing the macro-disparity between gamers having seizures, and permanent blackouts due to bullet wounds?
