Games like gravilon

A typical game among these

≈ 3.9M–5.3M copies

≈ $26.2M–$49.2M after Steam's cut

from ~72k 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: Portal 2 at ≈ 29.5M–48.0M copies, ≈ $81.1M–$218.1M 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 Puzzle (4 of 8).
The winners: Winners here lead with Platformer + Puzzle, priced around $10. The breakout hits carry Dark Humor + First-Person + Funny; a typical game here doesn't.
When they shipped: The similar games span 2007 to 2021, and none of them 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).
