Shenmue 3 will take up 100 GB of storage space on PC, developer Ys Net has revealed. The detail was included in a new updated posted on the game's Kickstarter page, which lists the PC system requirements. That is an unusually large amount of space, especially when you consider other open-world titles such as The Witcher 3: Wild Hunt and The Elder Scrolls V: Skyrim require considerably less (35 GB for the former, 12 GB for the latter). Take a look at the full system requirements below.
