I am sure there are bigger fans than me, but I have played and enjoyed all the Half Lifes and expansions up to this one. I love a good cinematic game. I have also enjoyed a number of Half Life mods over the years; They Hunger was a great zombie-themed campaign for the original Half Life, with more story and cinema than most hobbyist creations.

I remember finding Pandora Tomorrow’s multiplayer very interesting, with its extremely asymetric nature of 2 first-person Mercs vs. 2 third-person Spies. I do not know how the gameplay held up long-term, and it seemed like you needed to know all the details of every map to be remotely effective. But it was quite unique.
I understand that Chaos Theory had a similar competitive multiplayer, but I never tried it. I did play some of the cooperative multiplayer with my roommate, and had a good time.
