GOG games are DRM free, pretty easy to share with family. Saves might be tricker on a single deck, but the game itself may have multiple save slots.

The article says this build is for Steam Deck only, there won’t be a desktop release. At least, not with this build, maybe in the future.

Steam’s backup option is still there, and it can break the game files up into CD or DVD sized chunks for this exact purpose.

You do need to have Steam installed for the discs to work later.
