Games like Altitude

A typical game among these

≈ 49–456 copies

≈ $101–$358 after Steam's cut

from ~3 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: War Thunder at ≈ 49.7M–80.7M copies. It is a breakout hit, far above a typical game.

What their first month looked like

The games that made it here had under 15 reviews in their first month.

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

The genre you'd be entering

These games: The similar games share Side Scroller (6 of 8) and Flight (5 of 8).
The winners: Winners here lead with Simulation + Vehicular Combat. The breakout hits carry Free to Play + Simulation + Vehicular Combat; a typical game here doesn't.
When they shipped: The similar games span 2013 to 2022, and none of them 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 79 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
