Each platform measures its own player population.Why that matters
Each platform calculates rarity from its own player population. These percentages are shown side by side but are not a controlled comparison. Percentages are shown exactly as each platform publishes them — Pyroblast does not recalculate them or mix player populations together.
How hard is No Man's Sky?
Where the challenge is: systems — knowing how it works. You get through it by working out what the game is actually doing and coming back with a better build or a better plan, not by faster hands.
Finishing it
No Man's Sky has an ending, but nothing in its achievement list marks it clearly enough to trust — so there's no finish rate to show.

No Man's Sky is a game about exploration and survival in an infinite procedurally generated universe.
How rarity is calculated
Each platform calculates rarity from its own player population. These percentages are shown side by side but are not a controlled comparison.
- Steam — Valve's published global unlock percentage across Steam owners of the game.
- Xbox — Microsoft's published rarity percentage across Xbox players.
Percentages are shown exactly as each platform publishes them. Pyroblast does not recalculate them and does not mix player populations together. Data updated .
