A typical game among these

≈ $185.0M–$202.8M after Steam's cut

5 of the 8 similar games are hits.

About half the games that made it here had over 15 reviews in their first month; the range was 2 to 40k.

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

These games: The similar games share VR (5 of 8) and Co-op (3 of 8).
The winners: Winners here lead with Horror + Psychological Horror, priced around $20.
When they shipped: The similar games span 2017 to 2024, and 1 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 43 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
