Only the top fifth of 2019’s Steam releases earned about $34k gross, so plan for that or less.

4 of your 8 similar games are hits.

No genre covers most of your similar games. The closest is Interactive Fiction (4 of 8), so the genre you lead with is still undecided.

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: Left on Read at ≈ 130k–211k copies. A breakout hit, far above a typical game.

What it took to get here

About half the games that made it here had over 274 reviews in their first month; the spread ran 112 to 1k.

The genre you'd be entering

Your set: Your set clusters on Interactive Fiction (4 of 8) and Platformer (3 of 8).
The winners: Winners here lead with Romance + Simulation. The breakout hits carry Romance + Simulation + Choose Your Own Adventure; a typical game here doesn't.
The era: None of the games you compared shipped in the last two years; the newest is from 2023. That says more about your picks than about the market, so add newer similar games to read the timing.

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 of about 31, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
