Sea of Thieves is optimized for Xbox Series S by being more than 50% smaller in terms of install size. I don't know how the devs did it, but it's a hint for me that a SteamDeck optimized version could be possible. Valve already lists this game as "playable on Deck" and my only wish is if the devs could find a way to make it 20GB on Deck, like it's on Series S. I don't know what exactly makes the game smaller on Series S (PC version is 70GB, I believe) but if it's textures, perhaps it would be possible to make a "setting" in game to download high-res textures (like HALO Infinite does it) for people with a screen resolution higher than 1080p?
Basically, I am requesting that Sea of Thieves SteamDeck install size is as small as possible.
