Since Ghost of Tsushima can be pre-ordered now on the PlayStation Store, we have an idea of how big will be the installation file for Ghost of Tsushima. If the title is released exclusively for PlayStation 4 on July 17, 2020, the minimum installation size of Ghost of Tsushima should be 50 GB.
This number will surely increase as it is very likely that we will have to download a substantial Day One patch. The unveiling of Ghost of Tsushima’s installation size followed shortly after last week’s state of play, which focused solely on the game and showed the exploration, combat, and stealth aspects of the coveted title.
