A typical game among these

≈ 200k–356k copies

≈ $1.2M–$1.5M after Steam's cut

All 8 of the similar games are hits.

Best case: Sanctum 2 at ≈ 910k–1.5M copies, ≈ $3.7M–$10.1M after Steam's cut. It is a breakout hit, far above a typical game.

These games: The similar games share Tower Defense (8 of 8) and Sci-fi (6 of 8).
The winners: Winners here lead with Tower Defense, priced around $11. The breakout hits carry FPS + Online Co-Op + Mining; a typical game here doesn't.
When they shipped: The similar games span 2008 to 2025, 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 79 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
