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.

What it took to get here

About half the games that made it here had over 11k reviews in their first month; the spread ran 4k to 16k.

The genre you'd be entering

Your set: Your set clusters on Co-op (7 of 8) and Puzzle (6 of 8).
The winners: Winners here lead with Co-op + Puzzle, priced around $40. The breakout hits carry Split Screen + Local Co-Op + Story Rich; a typical game here doesn't.
The era: The games you compared span 2017 to 2023, 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 43 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
