What the Watch Dogs: Legion install size means in practice
The PC version is the largest listed build of Watch Dogs: Legion at 115.0 GB. Store listings show the size of the installed package, not the download; the transfer itself is usually 10–30 % smaller because the package is compressed on the way and unpacked on the console. Patches are added on top of the listed figure, so a game that has been out for a year commonly sits a few gigabytes above the number on its store page.
Watch Dogs: Legion is developed by Ubisoft Toronto and published by Ubisoft Entertainment. Genre: Shooter, Role-playing (RPG), Adventure. Platforms: PC, PS4, PS5, Xbox One, Xbox Series X|S.
Against the rest of the database, Watch Dogs: Legion at 115.0 GB sits above the average install of 43.0 GB across 446 games; 42 of them are larger. Within its genre the average is 43.9 GB, which puts Watch Dogs: Legion on the heavy side for a shooter of its generation. On a launch PS5 with 667 GB usable it takes 17 percent of the free space; on a 2 TB expansion drive about 6 percent. Deleting it frees exactly the listed figure plus any patches installed since the store listing was checked, and the saves stay.
