What is the Ghostwire: Tokyo file size?
Ghostwire: Tokyo recommends an SSD for minimum, and requires it under recommended system requirements. Thankfully, however, the Ghostwire: Tokyo file size is surprisingly small on PC via Steam.

You probably won't have to clear much space up or delete any other games, as the Ghostwire: Tokyo space requirement is only 20 GB. Keep in mind that this might change if there's a Day One update.
