The Orange Box
Half-Life Complete includes: Half-Life, Half-Life: Opposing Force, Half-Life: Blue Shift, Half-Life: Source, Half-Life 2, Half-Life 2: Deathmatch, Half-Life 2: Episode One, Half-Life 2: Episode Two, and Team Fortress Classic.
The Orange Box includes: Half-Life 2, Half-Life 2: Episode 1, Half-Life 2: Episode Two, Team Fortress 2, and Portal.
Why would Valve release their titles on a Steam rival? Put simply, the games still require the installation of Steam to run, so while Valve is only getting a fraction of the sales, they still get new Steam users.
