Games like Last Day of Rome

A typical game among these

≈ 866k–5.7M copies

≈ $22.3M–$58.8M after Steam's cut

from ~88k 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.

Best case: Slay the Spire at ≈ 6.3M–10.3M copies, ≈ $43.5M–$116.9M after Steam's cut.

What their first month looked like

About half the games that made it here had over 23 reviews in their first month; the range was 2 to 20k.

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

The genre you'd be entering

These games: The similar games share Card Game (8 of 8) and Card Battler (7 of 8).
The winners: Winners here lead with Roguelike Deckbuilder + Card Game, priced around $25.
When they shipped: Only 2 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 that falls with release age, from about 31 for the most recent game here to about 36 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
