Games like DOOM 3

A typical game among these

≈ 4.9M–11.7M copies

≈ $56.9M–$84.6M after Steam's cut

All 8 of the similar games are hits.

Best case: Half-Life 2 at ≈ 17.7M–28.8M copies, ≈ $48.6M–$130.7M after Steam's cut.

The genre you'd be entering

These games: The similar games share First-Person (8 of 8) and FPS (5 of 8).
The winners: Winners here lead with FPS + Sci-fi, priced around $10.
When they shipped: The similar games span 2004 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).
