All 8 of your similar games are hits.

Best case: Black Myth: Wukong at ≈ 30.0M–48.7M copies, ≈ $494.5M–$1329.5M after Steam's cut. A breakout hit, far above a typical game.

The genre you'd be entering
Your set
Your set clusters on Action RPG (4 of 8) and Open World (4 of 8).
The winners
Winners here lead with Mythology + Action RPG, priced around $60. The breakout hits carry Mythology + Souls-like + Story Rich; a typical game here doesn't.
The era
Only 3 of your 8 similar games shipped in the last two years. That says more about your picks than about the market, so add newer similar games to read the timing.
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).
