Games like XXZ

A typical game among these

≈ 637k–1.0M copies

≈ $2.2M–$6.5M after Steam's cut

from ~14k reviews

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

All 8 of the similar games are hits.

Best case: Resident Evil Village at ≈ 3.8M–6.2M copies, ≈ $42.2M–$113.5M after Steam's cut. It is a breakout hit, far above a typical game.

The genre you'd be entering

These games: The similar games share Sexual Content (6 of 8) and Anime (5 of 8).
The winners: Winners here lead with Survival Horror + Horror, priced around $40. The breakout hits carry Survival Horror + Horror + First-Person; 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).
