The genre you'd be entering

Your set: Your set clusters on Horror (6 of 8) and FPS (4 of 8).
The winners: Winners here lead with Sexual Content + FPS, priced around $35. The breakout hits carry Sexual Content + Hentai + Mature; a typical game here doesn't.
The era: Only 1 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).
