Most distinctive niche

(?)

Among all this game's genres, this is the one where players have the most distinctive taste — they rate games very differently from the average Steam gamer, suggesting a more passionate, selective community. It's not about what the game is most tagged as — it's about which of its communities has the most opinionated audience.

Reviewer Lifetime Playtime

Lifetime playtime reported by Steam for 500 sampled reviewers when the data was collected - non-reviewing owners excluded.

Mean significantly exceeds median - a small group of highly dedicated reviewers is pulling the average up. A passionate minority logs hundreds of hours while most reviewers finish their run or the whole story and move on. Classic pattern for sandboxes, roguelikes, and competitive games with infinite depth - the 'superfan tail' inflates the mean.
