WHY DO GAMERS CHEAT IN GAMES?

One of the methodologies of studying digital gamers according to Ricard Bartle's 'Four Suits' is the 'Spades.'

Originally, the Spades is a kind of trick taking card game originated in the United States at about 1930. But in Bartles context, it refers to players or gamers of digital video games who derives gratification from discovering a game's secret and hidden mechanics.

The vice of cheating in games has some what become a cultural practice. In recent times, game developers and their security companies have watched in agony as peripheral game industries grew producing information about games rather than games themselves. Sophisticated video game weapons that could take months of hard play to unlock can now easily be decoded in a matter of (how fast is your Internet connectivity?). There are even products sold that offers services to aid game cheats succeed, check out UKGamerCheats.com, cheatcc.com, gamecheats.eu and countless others. About.com has articles on top cheat codes, 'Fatal Frame cheats and secrets,' 'Resident Evil Cheats, Secrets and Unloakables for PS2' amongst others.
The question is why would people cheat on a game, doesn't that elude the whole concept and experience of gaming? I'm not an enthusiastic gamer- so what do I know?
Wikipedia explains it further though:

'Cheating in video games involves a player of a video game creating an advantage beyond the bounds of normal gameplay, usually to make the game easier. Cheats include advantages such as invulnerability ("God mode") or an infinite amount of some resource such as ammunition. Cheats may also create unusual or interesting effects which do not necessarily make the game easier to play, such as making enemies tougher, or giving characters (including enemies) different appearances, such as large heads. Cheats often take the form of 'secrets' placed by game developers, usually to reward dedicated players.

Cheats may be activated from within the game itself (a cheat code implemented by the original game developers); or created by third-party software (a game trainer) or hardware (a cheat cartridge).Examples of cheats in FPS games include the aimbot, which assists the player in aiming at the target, giving the user an unfair advantage, and the wallhack, which allows a player to see through solid or opaque objects and/or manipulate or remove textures, and ESP, with which the information of other players is displayed.'
