from ~43k reviews

Only the top fifth of 2019’s Steam releases earned about $34k gross, so plan for that or less.

All 8 of your similar games are hits.

Best case: Kingdom Come: Deliverance II at ≈ 4.8M–7.8M copies, ≈ $78.8M–$211.9M after Steam's cut. A breakout hit, far above a typical game.

The genre you'd be entering

Your set: Your set clusters on Story Rich (5 of 8) and Choices Matter (4 of 8).
The winners: Winners here lead with Story Rich, priced around $60. The breakout hits carry Story Rich + Time Travel + Singleplayer; a typical game here doesn't.
The era: The games you compared span 2015 to 2025, and 2 of your 7 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).
