Games like Space Guardian

A typical game among these

≈ 2k–44k copies

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

3 of the 8 similar games are hits.

No genre covers most of these similar games. The closest is Anime (4 of 8), so its genre is hard to place.

Of the 416 indie games that passed 1,000 reviews in 2022, 11.8% were novel genre mixes and 88.2% stuck to an established genre. Published indie market research.

Best case: Panzer Knights at ≈ 50k–81k copies, ≈ $343k–$923k after Steam's cut.

What their first month looked like

About half the games that made it here had over 43 reviews in their first month; the range was 2 to 507.

Games with under about 100 reviews in month one almost never recover.

The genre you'd be entering

These games: The similar games share Anime (4 of 8) and Action Roguelike (3 of 8).
The winners: Winners here lead with Tanks + Anime, priced around $25.
When they shipped: 4 of the 8 similar games shipped in the last two years, so this genre is actively shipping.

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 36 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
