Half-Life, come on

Alright, best game ever hands down; I have been so interested in playing this again, but due to my schedule and other games for which I am involved I cannot right now.
I know mr. hungry would play it and complete in a couple of hours, but that's because he's played it 12 times.
My goal is to finish Farcry, Bioshock and then Farcry 2 and then NOLF 1 and 2; from there it is open, but I do have priorities.
Talk about Half-Life here, favorite scene? Enemy? (Chumtoad)
