A typical game among these

≈ 1k–5k copies

≈ $3k–$15k after Steam's cut

from ~73 reviews

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

1 of the 8 similar games is a hit.

Best case: Voice of Cards: The Isle Dragon Roars at ≈ 36k–58k copies, ≈ $295k–$793k after Steam's cut. 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 45 reviews in their first month; the range was 10 to 544.

Games with under about 100 reviews in month one almost never recover.

The genre you'd be entering

These games: The similar games share Tabletop (7 of 8) and JRPG (4 of 8).
The winners: Winners here lead with Turn-Based + JRPG, priced around $30. The breakout hits carry Turn-Based + Card Battler + 2D; a typical game here doesn't.
When they shipped: Only 1 of the 8 similar games shipped in the last two years. 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).
