Games like Interstate 35

A typical game among these

≈ 269k–346k copies

≈ $1.4M–$2.6M after Steam's cut

from ~8k reviews

Only the top fifth of 2019's Steam releases earned $34k or more before Steam's cut, so plan for that or less.

All 8 of the similar games are hits.

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

What their first month looked like

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

The genre you'd be entering

These games: The similar games share 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.
When they shipped: The similar games span 2015 to 2024, and 2 of the 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).
