The genre you'd be entering

Your set: Your set clusters on Software (4 of 5) and Utilities (4 of 5).
The winners: Winners here lead with Mature + Utilities, priced around $5. The breakout hits carry Anime + First-Person + Mature; a typical game here doesn't.
The era: None of the games you compared shipped in the last two years; the newest is from 2018. That says more about your picks than about the market, so add newer similar games to read the timing.
