Games like Crazy Islands

A typical game among these

≈ 5.2M–29.2M copies

≈ $47.0M–$205.3M after Steam's cut

from ~380k 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: Rust at ≈ 42.7M–69.3M copies, ≈ $469.3M–$1261.8M after Steam's cut.

The genre you'd be entering

These games: The similar games share Open World (8 of 8) and Open World Survival Craft (8 of 8).
The winners: Winners here lead with Survival + Crafting, priced around $40.
When they shipped: None of the similar games shipped in the last two years; the newest is from 2022. That says more about which games were found than about the market.

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).
