Games like CastleStorm

A typical game among these

≈ 422k–1.2M copies

≈ $2.2M–$6.7M after Steam's cut

from ~20k reviews

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

3 of the 8 similar games are hits.

Best case: Thronefall at ≈ 589k–957k copies, ≈ $2.1M–$5.7M after Steam's cut.

What their first month looked like

About half the games that made it here had over 3 reviews in their first month; the range was 2 to 16k.

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

The genre you'd be entering

These games: The similar games share Tower Defense (7 of 8) and Fantasy (4 of 8).
The winners: Winners here lead with Tower Defense + City Builder, priced around $13.
When they shipped: The similar games span 2012 to 2025, 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).
