≈ 299k–536k copies

≈ $1.5M–$7.6M after Steam's cut

All 8 of the similar games are hits.

Best case: Among Us at ≈ 22.8M–37.0M copies, ≈ $31.3M–$84.0M after Steam's cut. It is a breakout hit, far above a typical game.

The genre you'd be entering

These games: The similar games share Space (6 of 8) and Sci-fi (5 of 8).
The winners: Winners here lead with Social Deduction + Space, priced around $5. The breakout hits carry Multiplayer + Social Deduction + Online Co-Op; a typical game here doesn't.
When they shipped: The similar games span 2012 to 2023, and none of them shipped in the last two years.

How these numbers were worked out

A hit here: 1,000+ reviews, roughly $150k+ before Steam's cut (a standard indie benchmark).

Copies come from each game's reviews times a sales-per-review rate that falls with release age, from about 31 for the most recent game here to about 79 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
