Games like Island Idle RPG

A typical game among these

≈ 486k–602k copies

≈ $494k–$919k after Steam's cut

from ~16k 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: IdleOn - The Incremental MMO at ≈ 741k–1.2M copies. It is a breakout hit, far above a typical game.

About half the games that made it here had over 4k reviews in their first month; the range was 678 to 26k.

The genre you'd be entering

These games: The similar games share Idler (7 of 8) and Simulation (6 of 8).
The winners: Winners here lead with Idler + Clicker. The breakout hits carry Free to Play + MMORPG + RPG; a typical game here doesn't.
When they shipped: The similar games span 2014 to 2025, and 3 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 70 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
