Starfield preload could start as early as August 9th. Relevant information was noticed on the Amazon website.
Recall that at the end of August, Bethesda and Microsoft are also preparing a Starfield presentation at gamescom 2023. The companies promise the “largest” Xbox booth with over 30 games shown.
Starfield releases September 6, 2023 for PC and Xbox Series (including Game Pass). The game will take up 125 GB of disk space, and its system requirements can be found here. Starfield recently received the Xbox Play Anywhere tag, which means digital buyers of the game will receive both the Xbox and PC versions at no additional cost.
