Games like Mind Keeper

A typical game among these

≈ 448k–677k copies

≈ $3.3M–$4.3M after Steam's cut

from ~14k 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: Dome Keeper at ≈ 558k–906k copies, ≈ $2.8M–$7.4M 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 3k reviews in their first month; the range was 3k to 8k.

The genre you'd be entering

These games: The similar games share Tower Defense (6 of 8) and Rogue-like (4 of 8).
The winners: Winners here lead with Post-apocalyptic + Rogue-like, priced around $18. The breakout hits carry Post-apocalyptic + Action + Combat; a typical game here doesn't.
When they shipped: The similar games span 2014 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 70 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
