Largest development team for a videogame

According to Red Dead Redemption 2 Producer Rob Nelson roughly 2,000 Rockstar employees worked on Arthur Morgan's adventures to life, of which 1,600 were engaged directly on the development of the game.

By contrast, GTA V had a development team of around 1000 (source: https://www.gamespot.com/articles/rockstar-more-than-1000-people-made-gtav/1100-6415330/)

Division 2 had slightly more at “over 1000” - which would reportedly make it the largest development team for an Ubisoft title. (source: https://gamerant.com/the-division-2-has-the-biggest-ubisoft-development-team-ever-318/)
