Many of you know this game, from the publicity it got from Counterstrike. Many of you counterstrike player's might not know of this game. But you should, this game back when it was released (1998) was ahead of its time, it introduced the puzzle element it FPS games, the cinematic feeling you got when you play the role of Gordon Freeman, a scientist working at the Black Mesa Anomalous Materials Research Center. If you haven't yet bought this game or haven't yet even tried it. It is definately a game you should have on your shelve at home. I have been seeing reviews right here on this sight saying that the graphics are dated, well duh... they are the game is 5 years old, and still kicking, with a multiplayer gaming community that is larger than Quake 3, Unreal Tournament 2003, & Battlefield 1942 combined. And is still growing. This game is a part of history, if you want to be involved in this history than I suggest you buy this game. This game has by far the most modifications out for it than any other game out there, with striving mod community's such as SvenCoop, Natural Selection, Science & Industry, & the yet to be released Half-life Rally.
