The middle of these games

≈ 145k–517k copies

≈ $1.2M–$4.0M after Steam's cut

from ~7k 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: Balatro at ≈ 4.9M–8.0M copies, ≈ $20.2M–$54.4M after Steam's cut. A breakout hit, far above a typical game.

What it took to get here
About half the games that made it here had over 4k reviews in their first month; the spread ran 1k to 21k.
The genre you'd be entering
Your set
Your set clusters on Rogue-like (8 of 8) and Card Game (7 of 8).
The winners
Winners here lead with Card Game + Roguelike Deckbuilder, priced around $15. The breakout hits carry Singleplayer + Replay Value + Pixel Graphics; a typical game here doesn't.
The era
Only 3 of your 8 similar games shipped in the last two years. 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).
