The unlikely success of “Outer Wilds”

• It’s another time-loop game in which the story progresses through numerous resets of the game’s universe.
• But it’s also a game in which you are strictly an outer space explorer, with nothing to shoot, break or kill — and nothing to collect and bring back to the next 22-minute loop other than knowledge about how its fantastic solar system works.
• The expansion’s contents have been kept secret (we won’t spoil anything here) other than that it offers some new, strange wonders to explore.

What they’re saying: “We want this to be a game about you exploring because you want to answer questions,” creative director Alex Beachum tells Axios, speaking of the original and its expansion.

• “Outer Wilds” is about the “intrinsic motivation” of curiosity, Beachum says.
• The original game contained a solar system of curiosities, each operating with its own looping systems for discovery, such as of a pair of planets called the “hourglass twins” that shed sand from one orb to the other, exposing explorable caves.

Between the lines: The dozen developers behind “Outer Wilds” started making “Echoes of the Eye,” just before the main game shipped.

• The main game was made in relative obscurity.
• Success has earned Beachum and the team a fanbase so motivated by their curiosity that they scour the expansion’s few pre-release screenshots to try to discern clues from the position of stars in the nighttime sky.

Beachum’s most startling discovery about his fans: Many have gotten tattoos of a symbol that players discover late in the main game.

• “I just remember one day we're just scribbling on the whiteboard,” he says of its creation. “And now it's like on people's bodies forever.”
