All 4 of your similar games are hits.

From a small set, so take it as a sketch.

No genre covers most of your similar games. The closest is Action-Adventure (2 of 4), 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: Trailmakers at ≈ 1.1M–1.8M copies, ≈ $7.7M–$20.6M after Steam's cut.

The genre you'd be entering

Your set: Your set clusters on Action-Adventure (2 of 4) and Racing (2 of 4).
The winners: Winners here lead with Space + Action-Adventure, priced around $25.
The era: None of the games you compared shipped in the last two years; the newest is from 2021. 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 31 for the most recent game here to about 36 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
