Cheating was exploited by technology-oriented players due to the difficulty of early cheats. However, a cheat industry emerged as gaming systems evolved, through the packaging and selling of cheating as a product. Cheat-enablers such as cheat books, game guides, cheat cartridges helped form a cheat industry and cemented cheating as part of gaming culture. However, cheating was not universally accepted in early gaming; gaming magazine "Amiga Power" condemned cheaters, taking the stance that cheating was not part of their philosophy of fairness. They also applied this in reverse; games should also not be allowed to cheat the player. Guides, walkthroughs, and tutorials are sometimes used to complete games but whether this is cheating is debated.
