Only the top fifth of 2019’s Steam releases earned about $34k gross, so plan for that or less.

All 8 of your similar games are hits.

No genre covers most of your similar games. The closest is First-Person (4 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: PUBG: BATTLEGROUNDS at ≈ 94.5M–153.6M copies. A breakout hit, far above a typical game.

The genre you'd be entering

Your set: Your set clusters on First-Person (4 of 8) and Co-op (3 of 8).
The winners: Winners here lead with Mature + Utilities, priced around $5. The breakout hits carry Mature + Utilities + Software; 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.

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 38 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).
