Games like Undead Citadel

A typical game among these

≈ 316–749 copies

≈ $1k–$3k after Steam's cut

from ~14 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: Half-Life: Alyx at ≈ 2.6M–4.3M copies, ≈ $43.2M–$116.1M 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 15 reviews in their first month; the range was 2 to 27k.

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

The genre you'd be entering

These games: The similar games share 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.
When they shipped: The similar games span 2017 to 2024, and 3 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 43 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
