2 of the 8 similar games are hits.

No genre covers most of these similar games. The closest is Tactical RPG (4 of 8), so its genre is hard to place.

Best case: 鬼谷八荒 Tale of Immortal at ≈ 5.6M–9.1M copies, ≈ $30.6M–$82.4M after Steam's cut. It is a breakout hit, far above a typical game.

The winners: Winners here lead with Tactical RPG, priced around $32. The breakout hits carry Tactical RPG + Management + Singleplayer; a typical game here doesn't.

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 43 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
