Games like X8

A typical game among these

≈ 4k–10k copies

≈ $61k–$149k after Steam's cut

from ~204 reviews

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

1 of the 8 similar games is a hit.

Best case: SUPERHOT VR at ≈ 334k–543k copies, ≈ $2.3M–$6.2M 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 149 reviews in their first month; the range was 50 to 303.

The genre you'd be entering

These games: The similar games share Shooter (7 of 8) and VR (7 of 8).
The winners: Winners here lead with VR + Shooter, priced around $25. The breakout hits carry Bullet Time + Puzzle + Time Manipulation; a typical game here doesn't.
When they shipped: 4 of the 8 similar games shipped in the last two years, so this genre 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 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).
