Games like Iron Brigade

A typical game among these

≈ 191k–841k copies

≈ $2.5M–$8.8M after Steam's cut

from ~12k 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: Bloons TD 6 at ≈ 12.0M–19.6M copies, ≈ $46.3M–$124.5M 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 536 reviews in their first month; the range was 421 to 4k.

The genre you'd be entering

These games: The similar games share Co-op (7 of 8) and Tower Defense (6 of 8).
The winners: Winners here lead with Tower Defense + Co-op, priced around $14. The breakout hits carry Family Friendly + Casual + Multiplayer; a typical game here doesn't.
When they shipped: The similar games span 2012 to 2023, 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).
