Valve is an entertainment software and technology company founded in 1996 and based in Bellevue, Washington. The company’s debut title, Half-Life®, has won over 50 Game of the Year Awards and was named "Best PC Game Ever" in the November 1999, October 2001, and April 2005 issues of PC Gamer, the world's best-selling PC games magazine.

Valve's portfolio of entertainment titles also includes Half-Life® 2, Counter-Strike®, Day of Defeat®, Team Fortress®, and Portal™. This portfolio of titles accounts for over 20 million retail units sold worldwide, and Valve games account for over 80% of the PC online action market.

oh my God, valve !!!!. ok. games that are made very very good. I was looking for something to communicate with you and I found it. I wanted you to know that if we could take the first Half-Life of the 1997 me and my brother are fans of you know that are 2 and valve makers who worked in a job MICROSOFT 2 years and another 3 years. also wanted to know if you can give me what is necessary to make a mod of Half-Life. We have not found any program to create mod. the valve hammer editor does not know very well use it. do not know how these things get darker screens, etc.. You are professionals and we want to know how to make a mod for HL. ah and by the way, the Source SDK is not ******* with it for any evil, I tell them where. I say "steam" that I have not found anything, or on the internet. ah and is said to google Buy Steam not even know why but I read in a web forum, this is not in another.

Valve = Best ever!!! I almost only play Valve games. I hardly ever play anything not made by Valve or something not made on Goldsource/Source engine. Unless it is something EXTREMELY awesome.(But nothing can ever compare to Valve.)
