Games like The Solus Project

A typical game among these

≈ 4.6M–5.4M copies

≈ $40.9M–$61.1M after Steam's cut

from ~139k 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: Fallout 4 at ≈ 21.0M–34.1M copies, ≈ $115.2M–$309.7M 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 Survival (7 of 8) and Exploration (6 of 8).
The winners: Winners here lead with Open World + Exploration, priced around $30.
When they shipped: The similar games span 2015 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 61 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
