Idle Sea of Thieves on Steam
Idle Sea of Thieves for Steam achievements and playtime
Sea of Thieves has a full Steam achievement list covering voyages, Tall Tales, and reputation milestones, most of which need real in-game progress through Rare's own account systems rather than anything idling can shortcut.
Idling here is mainly useful for Steam-tracked playtime, and for keeping Sea of Thieves in a multi-game idling rotation without launching its full client every time.

Frequently asked questions
Can idling unlock Sea of Thieves achievements?
Most Sea of Thieves achievements are tied to real voyage and reputation progress tracked through Rare's own systems, so they need to be earned by actually playing.
Does Sea of Thieves need an Xbox/Rare account linked to idle?
No - idling only interacts with Steam's own playtime tracking, not Rare's account services.
Is Sea of Thieves a Game Coordinator title?
No - it idles the same as any standard Steam game, through either Agent Mode or Legacy Sign In.
