PS5 discs can store up to 100 GB.

I would guess that most of that is textures.

They could probably reasonably just ship half-resolution textures on disc and make higher-res textures be a downloadable option. Bethesda did that with their games, later on added free, downloadable higher-res textures. Shouldn't require a lot of technical work. Maybe reducing texture resolution could trip some existing bug, a race condition somewhere, but it should be pretty mechanical, as changes go.

I don't really have a dog in this race---I wouldn't get the game either way. So I'm not pushing for that as an option. Just saying that I think that it's an option from a technical standpoint, if one wanted to provide a compact, on-disc version of the game.

A normal part of game optimization is making sure that it doesn’t take up all the storage space on every device.

What exam is in that game that justifies those file sizes?

Wonder if these 210gb are worth 210h of normal playtime. If the game is 20h long, all these textures and gigs are worthless.
