Games like SEMU

A typical game among these

≈ 28k–33k copies

≈ $157k–$240k after Steam's cut

from ~961 reviews

Only the top fifth of 2019's Steam releases earned $34k or more before Steam's cut, so plan for that or less.

4 of the 8 similar games are hits.

No genre covers most of these similar games. The closest is Interactive Fiction (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: Left on Read at ≈ 130k–211k copies. It is a breakout hit, far above a typical game.

What their first month looked like

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

The genre you'd be entering

These games: The similar games share 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.
When they shipped: None of the similar games shipped in the last two years; the newest is from 2023. That says more about which games were found than about the market.

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).
