After yesterdays news that Starfield might not have a physical disc, Bethesda has come in to clarify the following
Starfield Standard Edition is included with Xbox Game Pass. Game disc included with physical purchases of Xbox Standard Edition. Game code included with physical purchases on PC Standard edition.
The edition that contains the physical goodies (watch, steelbook etc.) doesn’t come with the disk but a digital download though. Honestly I never understood why they’d ship a steelbook without the physical game, but it’s pretty common these days.
