No internet? Games work offline and support LAN if you have a switch and a couple of consoles.
In 2026 I can still insert any used disc I bought in my ps3 and it will generate a (offline) client-side license for me and let me play and update the game with the disk inside just as a "proof" of still owning it.
If I'm online I'll get patches, else I'll just get served the version on the disc.
(Btw, ps3 also has a print spooler and can natively rip CDs and serve them while acting as a NAS. Or, you can stream games to your psp with remote play. It was truly a "let's cram everything we can inside" era and more like a proper pc with a mediacenter interface)
