All 8 of your similar games are hits.

No genre covers most of your similar games. The closest is FPS (3 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 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.
The era: The games you compared 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).
