A typical game among these

≈ 398k–589k copies

≈ $2.1M–$4.2M after Steam's cut

from ~11k reviews

Only the top fifth of 2019's Steam releases earned $34k or more before Steam's cut, so plan for that or less.

All 8 of the similar games are hits.

Best case: They Are Billions at ≈ 1.5M–2.4M copies, ≈ $12.2M–$32.9M after Steam's cut. It is a breakout hit, far above a typical game.

About half the games that made it here had over 5k reviews in their first month; the range was 4k to 7k.

The genre you'd be entering

These games: The similar games share RTS (5 of 8) and Tower Defense (5 of 8).
The winners: Winners here lead with Base-Building + Tower Defense, priced around $20. The breakout hits carry Base-Building + Tower Defense + Automation; a typical game here doesn't.
When they shipped: The similar games span 2013 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 79 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
