What is crunch in game development and why does it persist?
Crunch is extended periods of mandatory or expected overtime, often for months, in the run-up to a milestone or release. It is one of the industry's most persistent and most criticised practices.
What it looks like. Sixty to eighty hour weeks, six or seven days, sometimes sustained for a year. Documented consequences include burnout, physical illness, damaged relationships and people leaving the industry entirely — the average career length in games is notably short.
Why it happens, and the causes are structural rather than simply managerial failure:
Estimation is genuinely hard. As with delays generally, a game cannot be fully specified in advance because "fun" cannot be. Iteration is unpredictable, and schedules built on estimates of unpredictable work will be wrong.
Fixed release dates. Dates are committed to publishers, platform holders, marketing campaigns and retail long before the work is understood. When the schedule slips and the date cannot move, the only variable left is hours.
Scope creep and late changes, including from executives.
Dependency chains. Art, audio and QA wait on systems that slip, then have compressed time at the end regardless of their own planning.
Passion as leverage. Games attract people who want to make games, and that willingness is exploitable. "You're lucky to work here" is a documented dynamic.
Weak labour organisation. The industry has historically had very low unionisation, and much work is on short contracts or project-based, which discourages people from objecting. This is changing — several studios have unionised in recent years.
Salaried exemption means overtime is frequently unpaid.
Why it persists despite being counterproductive. Research outside games has consistently found that sustained overtime reduces total output — error rates rise, judgement degrades, and rework consumes the gains. Crunch produces short bursts followed by measurably worse work.
What has reduced it: public reporting, unionisation, some studios committing publicly against it, and a growing willingness to delay instead.
