4 of the 8 similar games are hits.

No genre covers most of these similar games. The closest is 2D Platformer (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: Super Meat Boy at ≈ 2.5M–4.0M copies, ≈ $10.2M–$27.5M 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 2D Platformer (4 of 8) and Platformer (4 of 8).
The winners: Winners here lead with Precision Platformer + Platformer, priced around $15. The breakout hits carry Pixel Graphics + Singleplayer + 2D; a typical game here doesn't.
When they shipped: The similar games span 2010 to 2022, 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).
