≈ 163–456 copies

≈ $213–$753 after Steam's cut

About half the games that made it here had over 7 reviews in their first month; the range was 2 to 536.

The genre you'd be entering

These games: The similar games share Tower Defense (7 of 8) and Rogue-lite (5 of 8).
The winners: Winners here lead with Top-Down Shooter + Mechs, priced around $12. The breakout hits carry Mechs + Anime + Singleplayer; a typical game here doesn't.
When they shipped: 5 of the 8 similar games shipped in the last two years. You'd be launching into a busy stretch.

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 of about 31, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
