All 8 of your similar games are hits.

No genre covers most of your similar games. The closest is Co-op (4 of 8), so the genre you lead with is still undecided.

Best case: R.E.P.O. at ≈ 10.4M–17.0M copies, ≈ $28.7M–$77.0M after Steam's cut. A breakout hit, far above a typical game.

The genre you'd be entering

Your set: Your set clusters on Co-op (4 of 8) and First-Person (4 of 8).
The winners: Winners here lead with Co-op, priced around $20. The breakout hits carry Co-op + Horror + Physics; a typical game here doesn't.
The era: The games you compared span 2009 to 2025, and 1 of your 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).
