7 of your 8 similar games are hits.

No genre covers most of your similar games. The closest is Anime (2 of 8), so the genre you lead with is still undecided.

Of the 416 indie games that passed 1,000 reviews in 2022, 11.8% were novel genre mixes and 88.2% stuck to an established genre. Published indie market research.

Best case: Wallpaper Engine at ≈ 30.8M–50.0M copies, ≈ $42.2M–$113.5M after Steam's cut.

The genre you'd be entering

Your set: Your set clusters on Anime (2 of 8) and First-Person (2 of 8).
The winners: Winners here lead with Mature + Utilities, priced around $5.
The era: None of the games you compared shipped in the last two years; the newest is from 2020. 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 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).
