The middle of these games

≈ 452k–701k copies

≈ $3.4M–$4.3M after Steam's cut

from ~14k 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: Slay the Spire at ≈ 6.3M–10.2M copies, ≈ $43.1M–$116.0M 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 9k reviews in their first month; the spread ran 1k to 21k.

The genre you'd be entering

Your set: Your set clusters on Card Game (6 of 8) and Deckbuilding (6 of 8).
The winners: Winners here lead with Roguelike Deckbuilder + Card Game, priced around $20. The breakout hits carry Singleplayer + Roguelike Deckbuilder + Rogue-like; a typical game here doesn't.
The era: The games you compared span 2018 to 2024, and 2 of your 8 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 38 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
