GoldSrc
Valve developed a number of titles using the GoldSrc engine, many of which were based on original user-made modifications of "Half-Life". "Team Fortress Classic", released officially by Valve Corporation in 1999, was one of such games (based on an older Quake mod, "Team Fortress"). "Counter-Strike", "Ricochet", and "Day of Defeat" were also originally modifications, the rights to which were purchased by Valve. "Counter-Strike" evolved into its own series with the release of "" in 2004, and while "" ran on the Source engine, further games in the series still used GoldSrc. "Counter-Strike Neo", "Counter-Strike Online", and "", released in 2005, 2008, and 2014 respectively, utilized GoldSrc as their basis, despite the development of the Source engine having been completed and the first version released.
