In the video game industry, crunch is compulsory overtime during the development of a game. Crunch is common in the industry and can lead to work weeks of 65–80 hours for extended periods of time, often uncompensated beyond the normal working hours. It is often used as a way to cut the costs of game development, a labour-intensive endeavour. However, it leads to negative health impacts for game developers and a decrease in the quality of their work, as well as driving people out of the industry temporarily or permanently. Critics of crunch note how it has become normalized within the game-development industry, to deleterious effects for all involved. A lack of unionization on the part of game developers has often been suggested as the reason crunch exists, and organizations such as Game Workers Unite aim to fight against crunch by forcing studios to honour developers' labor rights. "Crunch time" is the point at which the team is thought to be failing to achieve milestones needed to launch a game on schedule. The complexity of work flow, reliance on third-party deliverables, and the intangibles of artistic and aesthetic demands in video-game creation create difficulty in predicting milestones. The use of crunch time is also seen to be exploitative of the younger male-dominated workforce in video games, who have not had the time to establish a family and who were eager to advance within the industry by working long hours. In some cases, the drive for crunch may come from the developers themselves as individual developers may want to work extra hours without a mandate to assure their product meets delivery milestones and is of high quality, which can influence other developers to also commit to extra hours or avoid taking time off as to appear slacking. Because crunch time tends to come from a combination of corporate practices as well as peer influence, the term "crunch culture" is often used to discuss video game development settings where crunch time may be seen as the norm rather than the exception.
