"Valve-ware" has become the industrial term used jokingly with game releases by Valve Software, used to acknowledge Valve's ability to buy or acquire 3rd party developers for game ideas(Team Fortress, Counter Strike, Portals, Left 4 Dead, etc.) and release the games in a incomplete state. After additional time and money from sales Valve will possibly fix said games post release with 100s of patches. If they are unable to post-release patch, Valve has an alternate plan to blame someone else for their poor quality.

List of game mods or game developers acquired:

Counter Strike (Half-Life modification by Minh "Gooseman" Le and Jess "Cliffe" Cliffe, later hired by Valve)

Team Fortress (Team Fortress was originally a 1996 QuakeWorld mod. Its developers were working on Team Fortress 2 as a standalone game, but later joined Valve Software and ported the original as a mod for Half-Life called Team Fortress Classic in April 1999.)

Portals (Portal is Valve's spiritual successor to the freeware game Narbacular Drop, the 2005 independent game released by students of the DigiPen Institute of Technology; the original Narbacular Drop team is now employed at Valve. The Portals concept actually comes from the video game Prey which was in development since the mid-90s.)

Left 4 Dead (It was developed by Turtle Rock Studios, which was purchased by Valve Corporation during development.)

Alien Swarm (It is a remake of the Alien Swarm mod for Unreal Tournament 2004, and it was developed by the original team, which was hired by Valve during the course of the development process.)

Day of Defeat (DoD began as a Half-Life 3rd party mod in 2000. Later, the DoD team joined Valve Software and produced a standalone version published through Activision.)

Dota2 (a sequel to the Warcraft III: The Frozen Throne custom scenario Defense of the Ancients.)
