≈ $121.0M–$183.7M after Steam's cut

All 8 of the similar games are hits.

These similar games lean toward the genre's biggest winners; the typical figure comes from its ordinary successes.

The genre you'd be entering

These games: The similar games share Grand Strategy (7 of 8) and Historical (7 of 8).
The winners: Winners here lead with Turn-Based Strategy + Historical, priced around $50. The breakout hits carry Multiplayer + Turn-Based Strategy + Singleplayer; a typical game here doesn't.
When they shipped: The similar games span 2010 to 2020, 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 79 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
