Edit - broke your quote, apologies - I input the same question as google.
Grok does a much better job of adding some clarification. Same input from me
No, 70% of Naughty Dog's overall staff did not leave after Uncharted 4 (released in 2016). The figure specifically refers to
non-lead designers credited on that game: out of about 20 non-lead designers, 14 (70%) had left the studio by around 2018–2020.
This detail comes primarily from a March 2020
Kotaku report by Jason Schreier on crunch culture at Naughty Dog during
The Last of Us Part II's development. It highlighted high turnover linked to intense crunch (long hours, including up to 12+ hour days and weekends) on
Uncharted 4 and subsequent projects. Many veterans, including co-director Bruce Straley (who left in 2017 after feeling burnt out), departed, leading to a design team for
TLOU Part II that was reportedly ~70% new to the studio. A significant number of artists also left.
- Not the whole studio: Naughty Dog had hundreds of employees (estimates around 200–400+ in that era, growing to 400+ by 2023). The 70% applied narrowly to a subset of the design team, not the entire staff, leads, or other departments. One Reddit discussion even noted it equated to roughly 3–4% of total employees when viewed broadly.
- Turnover was an issue, but not unprecedented for the studio: Naughty Dog has a history of post-project attrition due to its demanding "crunch" culture (well-documented across The Last of Us, Uncharted 4, and The Lost Legacy). Studio leaders downplayed similar exits earlier (e.g., in 2014 after Amy Hennig and others left during Uncharted 4's troubled development). Industry-wide game dev turnover is often high (~15% or more annually in some reports), but Naughty Dog's was notably elevated in the design area.
- Causes: Reports pointed to burnout from extreme schedules on Uncharted 4 (described by some as the "worst crunch" they'd experienced), with the studio then relying more on less experienced hires and contractors for the next project—which reportedly worsened the cycle.
- Later developments: There were additional exits, contract non-renewals (e.g., ~25 contractors, mostly QA, in 2023), and broader PlayStation layoffs affecting Naughty Dog in 2024. However, the studio continued shipping major titles and maintained a large team.
In short, the "70%" claim is a real and often-cited statistic—but it's frequently overstated online as "70% of the studio" or "most staff" leaving en masse right after
Uncharted 4. It was a serious (and department-specific) turnover rate tied to working conditions, not a near-total exodus of the entire company. Naughty Dog has faced ongoing criticism for crunch and retention issues over the years.
I love sensational percentages that are used by businesses and news sites.
