Games like 18Korea

A typical game among these

≈ 182k–390k copies

≈ $1.4M–$3.1M after Steam's cut

from ~9k reviews

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

All 8 of the similar games are hits.

Best case: Business Tour - Board Game with Online Multiplayer at ≈ 2.8M–4.5M copies. It is a breakout hit, far above a typical game.

The genre you'd be entering

These games: The similar games share Board Game (6 of 8) and Tabletop (6 of 8).
The winners: Winners here lead with Board Game, priced around $15. The breakout hits carry Card Game + Multiplayer; a typical game here doesn't.
When they shipped: The similar games span 2015 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 61 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
