The relevant section is blunt. “The Software is licensed to you, not sold,” the EULA states. “You are granted a limited, non-exclusive, non-transferable, and personal license to play or use the Software for your private, non-commercial use on the system or device it was intended for.”
The terms also restrict renting, modifying, or obtaining games through unauthorised means. Nothing in there is new, technically. Sony’s EULA has always said this. The timing is what makes it land differently right now.
I interpret that as Steam covering for some enhittified games on their store that require a constant internet connection.
For example several games I have in my Steam library work fine offline.
But the Megaman Battle Network remake subtly requires an internet connection to start the gamea from the title screen.
Very misleading as the game technically boots offline but you can’t leave the title screen.
