Girl Playing Video Games

Many games produced for the PC are designed such that technically oriented consumers can modify the game. These mods can add an extra dimension of replayability and interest. Developers such as id Software, Valve Software, Crytek, Bethesda, Epic Games and Blizzard Entertainment ship their games with some of the development tools used to make the game, along with documentation to assist mod developers. The Internet provides an inexpensive medium to promote and distribute mods, and they may be a factor in the commercial success of some games. This allows for the kind of success seen by popular mods such as the Half-Life mod Counter-Strike.
Cheating
Cheating in computer games may involve cheat codes and hidden spots implemented by the game developers, modification of game code by third parties, or players exploiting a software glitch. Modifications are facilitated by either cheat cartridge hardware or a software trainer. Cheats usually make the game easier by providing an unlimited amount of some resource; for example weapons, health, or ammunition; or perhaps the ability to walk through walls. Other cheats might give access to otherwise unplayable levels or provide unusual or amusing features, like altered game colors or other graphical appearances.
