The middle of these games

≈ 254k–316k copies

≈ $1.4M–$1.7M after Steam's cut

from ~5k reviews

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

All 8 of your similar games are hits.

Best case: Hacknet at ≈ 1.3M–2.1M copies, ≈ $3.5M–$9.4M after Steam's cut. A breakout hit, far above a typical game.

The genre you'd be entering

Your set: Your set clusters on Programming (8 of 8) and Puzzle (7 of 8).
The winners: Winners here lead with Hacking + Simulation, priced around $10. The breakout hits carry Typing + Story Rich + Choices Matter; a typical game here doesn't.
The era: The games you compared span 2011 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).
