≈ $2.4M–$3.5M after Steam's cut

Games with under about 100 reviews in month one almost never recover.

The winners: Winners here lead with 4 Player Local + 2D Fighter, priced around $10.
When they shipped: The similar games span 2013 to 2025, and 3 of the 8 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).
