A typical game among these

≈ 5.5M–6.5M copies

≈ $41.0M–$82.9M after Steam's cut

from ~180k 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: Stardew Valley at ≈ 43.5M–70.7M copies, ≈ $179.4M–$482.4M 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 21k reviews in their first month; the range was 951 to 43k.

The genre you'd be entering

These games: The similar games share Simulation (5 of 8) and Automobile Sim (2 of 8).
The winners: Winners here lead with Simulation, priced around $17. The breakout hits carry Relaxing + Farming Sim + Multiplayer; a typical game here doesn't.
When they shipped: The similar games span 2012 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 79 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
