The middle of these games

≈ 944–1k copies

≈ $2k after Steam's cut

from ~30 reviews

Only the top fifth of 2019’s Steam releases earned about $34k gross, so plan for that or less.

None of your 8 similar games are hits.

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

What it took to get here

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

Under about 100 in month one, almost nothing recovers.

The genre you'd be entering

Your set: Your set clusters on 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 + RPG + RTS; a typical game here doesn't.
The era: 4 of your 8 similar games shipped in the last two years, so this niche 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).
