Xbox One comes with 500 GB available on the hard drive, but that space will fill up fast for anyone who plans on playing a lot of games. Every Xbox One videogame has a mandatory install regardless of whether it is a physical or digital copy. Thanks to one Target consumer receiving his Xbox One early, Twitter user Moonlightswami revealed Call of Duty: Ghosts is 39 GB to install. More users posted to NeoGAF the install sizes for other Xbox One games and noted discs install automatically when inserted and some games are playable during installation. Call of Duty: Ghosts was available to play after installation reached 51%.
