A typical game among these

≈ 773k–1.6M copies

≈ $4.1M–$11.1M after Steam's cut

All 8 of the similar games are hits.

Best case: 7 Days to Die at ≈ 9.9M–16.2M copies, ≈ $123.1M–$331.0M 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 Tower Defense (6 of 8) and Base-Building (3 of 8).
The winners: Winners here lead with Survival + Zombies, priced around $14. The breakout hits carry Singleplayer; 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).
