All 8 of the similar games are hits.

No genre covers most of these similar games. The closest is Co-op (4 of 8), so its genre is hard to place.

Of the 416 indie games that passed 1,000 reviews in 2022, 11.8% were novel genre mixes and 88.2% stuck to an established genre. Published indie market research.

Best case: R.E.P.O. at ≈ 10.6M–17.2M copies, ≈ $29.1M–$78.2M 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 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.
When they shipped: The similar games span 2009 to 2025, 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 79 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
