Games like Horse Farm

A typical game among these

≈ 3.7M–5.9M copies

≈ $48.5M–$59.1M after Steam's cut

from ~93k 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: People Playground at ≈ 9.2M–15.0M copies, ≈ $25.4M–$68.2M 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 Sandbox (6 of 8) and Simulation (5 of 8).
The winners: Winners here lead with Sandbox, priced around $20. The breakout hits carry Moddable + Singleplayer; a typical game here doesn't.
When they shipped: None of the similar games shipped in the last two years; the newest is from 2020. That says more about which games were found than about the market.

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 61 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
