The middle of these games

≈ 316–749 copies

≈ $1k–$3k after Steam's cut

from ~14 reviews

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

3 of your 8 similar games are hits.

Best case: Half-Life: Alyx at ≈ 2.6M–4.2M copies, ≈ $43.0M–$115.5M 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 15 reviews in their first month; the spread ran 2 to 27k.

Under about 100 in month one, almost nothing recovers.

The genre you'd be entering

Your set: Your set clusters on VR (7 of 8) and FPS (4 of 8).
The winners: Winners here lead with VR, priced around $25. The breakout hits carry Singleplayer + First-Person; a typical game here doesn't.
The era: The games you compared span 2017 to 2024, and 3 of your 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 43 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
