How many copies did Star Defence sell?

Q: How many copies did Star Defence sell?

25 to 40 copies, based on its 1 Steam reviews. This is a labeled estimate from the review count, not exact sales.

Estimated copies sold: ≈ 25–40; $7–$18 after Steam's cut $12–$28 before Steam's cut; from 1 review (1 user reviews); Only 1 review so far, so that range swings on one or two people. Read it as a hint, not a measurement.

Copies are estimated from the public review count, adjusted for release year, and cross-checked against SteamSpy's own estimate.

Games like Star Defence

A typical game among these

≈ 537–944 copies

≈ $646–$2k after Steam's cut

from ~19 reviews

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

None of the 8 similar games are hits.

Best case: Bees vs Zombees at ≈ 3k–4k copies, ≈ $6k–$16k after Steam's cut. It is a breakout hit, far above a typical game.

What their first month looked like

About half the games that made it here had over 14 reviews in their first month; the range was 8 to 59.

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

The genre you'd be entering

These games: The similar games share Bullet Hell (8 of 8) and Tower Defense (8 of 8).
The winners: Winners here lead with Bullet Hell + Tower Defense, priced around $8. The breakout hits carry Wargame + Singleplayer + RPG; a typical game here doesn't.
When they shipped: 4 of the 8 similar games shipped in the last two years, so this genre is actively shipping.

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 of about 31, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
