Games like Bubble Siege

A typical game among these

≈ 619–3k copies

≈ $3k–$9k after Steam's cut

from ~33 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: Out of Ammo at ≈ 31k–50k copies, ≈ $84k–$226k after Steam's cut. It is a breakout hit, far above a typical game.

About half the games that made it here had over 10 reviews in their first month; the range was 9 to 14.

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 VR (7 of 8).
The winners: Winners here lead with VR + FPS, priced around $10. The breakout hits carry Singleplayer; a typical game here doesn't.
When they shipped: The similar games span 2014 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 70 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
