Games like Interstate 35

The middle of these games

≈ 268k–344k copies

≈ $1.4M–$2.6M after Steam's cut

from ~8k reviews

Only the top fifth of 2019’s Steam releases earned about $34k gross, so plan for that or less.

All 8 of your similar games are hits.

Best case: Mirror 2: Project X at ≈ 2.9M–4.7M copies, ≈ $1.6M–$4.2M after Steam's cut. A breakout hit, far above a typical game.

What it took to get here

About half the games that made it here had over 2k reviews in their first month; the spread ran 1k to 23k.

The genre you'd be entering

Your set: Your set clusters on Visual Novel (7 of 8) and Female Protagonist (6 of 8).
The winners: Winners here lead with Match 3 + Anime, priced around $2. The breakout hits carry 3D + Match 3 + Drama; a typical game here doesn't.
The era: The games you compared span 2015 to 2024, and 2 of your 8 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 61 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
