You can expect Sea of Stars to take around 25–30 hours to beat for a typical first playthrough focusing mainly on the story, with 20-ish hours on the low end and 40+ hours if you chase everything.

Main story: how long to beat Sea of Stars

Most players report:

  • Around 23–26 hours to finish the main story and reach the credits if you do a normal amount of side content.
  • Faster runs can come in just under 21–23 hours if you know where to go and skip most extras.

A good rule of thumb: if you play a couple of evenings per week, it feels like a “one-to-two week” RPG rather than a months-long epic.

Completionist and true ending time

If you like to explore every corner:

  • True ending / full side content: usually 30–35 hours , depending on how quickly you solve puzzles and track down optional objectives.
  • Full completion (achievements, secrets, minigames, etc.): often around 40 hours or a bit more.

Players who go for endgame extras, secret bosses, and best gear tend to cross that 35–40 hour mark without grinding-heavy gameplay.
