A typical game among these

≈ 13.6M–27.0M copies

≈ $173.0M–$286.9M after Steam's cut

All 8 of the similar games are hits.

The genre you'd be entering

These games: The similar games share Survival (8 of 8) and Open World (6 of 8).
The winners: Winners here lead with Co-op + Survival, priced around $15. The breakout hits carry Co-op + Online Co-Op + Gore; a typical game here doesn't.
When they shipped: The similar games span 2009 to 2024, and 2 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).
