≈ $57.6M after Steam's cut

from ~678k reviews

Only the top fifth of 2019's Steam releases earned $34k or more before Steam's cut, so plan for that or less.

All 8 of the similar games are hits.

No genre covers most of these similar games. The closest is FPS (3 of 8), so its genre is hard to place.

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 ≈ 95.8M–155.7M copies. It is a breakout hit, far above a typical game.

The genre you'd be entering

These games: The similar games share FPS (3 of 8) and Battle Royale (2 of 8).
The winners: Winners here lead with Survival + Shooter. The breakout hits carry PvP + Survival + Shooter; a typical game here doesn't.
When they shipped: The similar games span 2007 to 2020, and none of them shipped in the last two years.

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 79 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
