I only got to play HL2 when it was released to the PS3 as the Orange Box. I have everything HL on my steam account but I never played them there hah.
Not a big fan of HL2 anyway. HL1 is still the better game for me. Spent a lot of time playing the Sierra CDROM version, not to mention the huge amount of hours spent playing around with Worldcraft (now Hammer) making custom campaign maps for myself to play... I was so glad my PC at the time could run it at 1024x768 at 30fps, in a way it was the 4K res of the time lol. Still my favorite PC game ever.
I'm not a big fan of the direction the game went Xen onwards, and that includes all subsequent games, which are great but not as great as HL1, because I love the concept of "In this game shit has just hit the fan. Escape" it has, which is a little bit subdued in the sequel and episodes.
