All 8 of the similar games are hits.

No genre covers most of these similar games. The closest is Horror (4 of 8), so its genre is hard to place.

Best case: The Forest at ≈ 20.8M–33.7M copies, ≈ $114.2M–$306.9M after Steam's cut. It is a breakout hit, far above a typical game.

The genre you'd be entering

These games: The similar games share Horror (4 of 8) and Survival Horror (3 of 8).

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).
