Games like Castle of Illusion

A typical game among these

≈ 277k–660k copies

≈ $2.1M–$3.8M after Steam's cut

from ~8k 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: Sonic Mania at ≈ 995k–1.6M copies, ≈ $5.5M–$14.7M 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 Platformer (6 of 8) and Classic (4 of 8).
The winners: Winners here lead with Classic, priced around $40. The breakout hits carry Classic + 3D Platformer; a typical game here doesn't.
When they shipped: The similar games span 2011 to 2024, 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).
