“Turns every rope into four-person teamwork and lets shared seas rewrite the script, aged from a rocky launch into a six-year mainstay”
編集部の総評
The story of Sea of Thieves is itself a parable about persistence. How does a game with a lukewarm launch reputation age into an evergreen?
From a rocky launch to the eighth generation's most successful new IP
Trace its arc and you find a genuinely inspiring comeback.

At its 2018 launch the 67 on Metacritic was nothing to celebrate, and the "hollow" charge briefly drowned out how dazzling its sailing design was — some onlookers flatly predicted the game would not last a year. Rare refused to fold, and six years of sustained operation turned the whole thing around. Sea of Thieves now counts 40 million players to date and is widely regarded as Microsoft's most successful original intellectual property of the eighth generation, a near-miracle for a brand-new IP. It took the 2021 BAFTA award for Evolving Game and was nominated again for the same category in 2025 — the industry's most authoritative nod to the long-term evolution at its core. The durable 89% positive rating on Steam confirms from the player side that the finished article of today and the half-built launch of old are already a generation apart. Sea of Thieves proved a simple thing with its own life: a game on a solid foundation, given long enough investment, can genuinely rewrite its fate.
Who should buy it, and who should hesitate
History settled, the practical question arrives: is this game actually for you?

If you can muster a steady crew of friends, savour the synced rhythm of four people working the sails, relish the live battle of wits against strangers at sea, and won't stew over hard-won treasure that might get carried off — then Sea of Thieves is all but tailored to you, and the joy it offers has no substitute. Flip every one of those and the warning is just as clear: if you are wired for solo number-crunching, need steady and legible progression rewards, can't stomach the sting of effort coming to nothing, or simply have no reliable companions to sail with, weigh it with real care. The pleasure of this ocean is built on that very uncertainty, and forcing yourself through it only chafes.
A last word on why it can't be replaced. The remarkable thing about Sea of Thieves is the way it welds co-op sailing to live player encounters so tightly that it spins up an emergent narrative no one could ever script. Direct rival Skull and Bones tried to carve a slice from the same genre, but by cutting the boarding melees and the player drama it never reproduced that particular chemistry.
That chemistry is the whole game. Strip it out and you have a pretty sailing simulator; leave it in and you have something nobody else has managed to bottle. After a six-year voyage, that is precisely why Sea of Thieves still sits steady on the throne of pirate games, and why no challenger has yet found a way to push it off.
